▼ Conjugated polymers have been explored as an important class of organic electronics, such as organic light emitting diodes (OLEDs), organic field-effect transistors (OFETs) and organic solar cells. With the development of various synthetic methods and characterization techniques, the family of conjugated polymers have grown to a scope which goes beyond any single discipline. Functionalization of conjugated organic systems with main group elements represents an active research area of significant interest in the scientific community. One of the most employed elements is the electron-deficient boron that features an empty p orbital that enables the overlap with π orbitals of attached aryl groups. This leads to novel optical and electronic properties for organoborane containing conjugated polymers. The focus of this thesis is on the investigation of incorporation of organoborane into different conjugated systems. Chapter 1. Regioregular Organoborane-Functionalized Poly(3-alkynylthiophene)s A series of new alkynylphenylborane-functionalized monomers were synthesized and utilized to prepare regioregular borane acceptor-functionalized polythiophenes rr-P1, rr-P2 using Stille-type polymerization and P1 using Kumada technique. Theoretical calculations on model systems and fluoride anion binding studies confirm the assignment of the lowest energy absorption at ca. 500 nm to the polymer backbone and the higher energy bands at ca. 330-340 nm to a charge transfer state which is localized on the borane moieties. A comparison between polymer P1 and rr-P1 suggests a higher regioregularity which results in significant bathochromic shifts in both absorption and emission spectra. The borane acceptor effect is also reflected in the bathochromic shift of the lower energy absorption maximum of polymers rr-P1, rr-P2 and rr-P3HT which is envisioned as possible candidates for optical and sensory materials. Chapter 2. Amphiphilic Polythiophene Block Copolymers Containing Phenylboronic Acid Functionality The amphiphilic block copolymers poly (3-hexylthiophene)-block-polystyrene boronic acid (P3HT-b-PSBA) and poly (3-hexylthiophene)-block-poly (4-vinylpyridine-stat-styrene boronic acid) (P3HT-b-P(4VP-stat-SBA) are prepared using a combination of Grignard metathesis (GRIM), controlled radical polymerization (CRP) and click chemistry. This polymers represent a new type amphiphilic polythiophene block copolymers containing boronic acid-functionality for potential applications in material chemistry. Chapter 3. The First 1, 2-azaborine Polymer With a collaborative effort with Prof. Liu’s group (Boston College) who provided Bpin/Br-functionalized AB-type monomers and regioregular model compounds, we incorporated monocyclic 1,2-azaborine into extended π-conjugated systems using the Suzuki-Miyaura polymerization technique. Though the polymer main chain is isoelectronic to poly (paraphenylene), photophysical and computational studies indicate a closer similarity to polyacetylene which indicates promising applications as a new… Advisors/Committee Members: Jäkle, Frieder (chair), Pietrangelo, Agostino (internal member), Sheridan, John (internal member), Hu, Qiao-Sheng (outside member).

▼ Organic bioelectronics is the convergence of organic electronics and biology. Motivated by the unique combination of both electronic and ionic conductivity, organic semiconducting materials have been applied in OECTs for sensing applications to translate bio-logical signals into a quantitative electrical reading. Due to their carbon-based structure and flexibility, CPs can achieve improved biocompatibility compared to inorganic devices as they are intrinsically “softer”, avoiding mechanical mismatch and the need for surface compatibilizing layers. These promising materials have broad potential to be used in applications such as biosensors, drug delivery, and neural interfaces. In the second chapter, a series of lysine-functionalized DPP3T semiconducting polymers, outline their synthesis, and demonstrate that these particular polymers allow neuron cells to adhere and grow, in comparison to unfunctionalized polymers, where cells quickly die. Through covalent attachment of small lysine units, the conjugated polymer backbone and cells can directly electrically communicate, favorable for neural signals recording/stimulating. In the third chapter, NDI-based semiconducting polymers are selected for lysinefunctionalization, giving protein-like surfaces for neurons to attach, grow and form a network without the need of an intermediate PDL coating. Most importantly, this careful choice of NDI backbone allows lysinated-NDI polymers to operate in OECTs with an outstanding normalized transconductance value of 0.25 S/cm. In the fourth chapter, a new technique is presented to biofunctionalize thin film surface of polymers. Two methods including CuAAC and thiol-ene click are demonstrated to be applicable to biofunctionalize surface. In particular, both of them can achieve biocompatible surface by attaching biomolecules at high density while maintaining electrically conductive film. In the final chapter, three series of NDI-T2 are presented synthesized via Stille coupling reaction using different Pd catalysts. Following electrochemical and device characterization, the study of the influence of spacers between backbone and EG chain for performance in OFET and OECT operations is carried out. It is clearly evidenced that electron mobility increases by a factor of 10 with gradual increased spacers for all polymers in OFETs devices. For OECTs, within three series, pNDI-Cx-T2 stands out, especially pNDI-C4-T2 giving the highest reported transconductance at 0.479 S/cm and a low threshold voltage of 0.18 V.

▼ Of fundamental importance to the advancement of next-generation technologies using organic electronic materials is the development of new synthetic methodologies and the investigation of novel material properties. Thiazoles have been reported in conjugated organic molecules and polymers for well over two decades; however, various aspects of these distinct heterocycles have thus far been overlooked and undervalued. This thesis will report our efforts to exploit both the reactivity and properties of thiazole in order to develop new methods for the synthesis of conjugated materials, and to produce conjugated small molecules and polymers with unique properties. First, our work towards the development of a new transition metal-free condensation reaction for the synthesis of poly(hetero)arenes will be discussed. This reaction utilizes a protecting group strategy, and the unique reactivity of readily accessible thiazole-N-oxides, in order to realize a wide range of bithiazole-N-oxide conjugated small molecules and polymers. In the following section, these bithiazole-N-oxides are explored as a new class of conjugated materials in an extensive joint experimental and computational study. This study revealed a notably strong non-covalent S – O interaction found in the bithiazole-N-oxide core, the effects of which are examined on the optical, electrochemical, and physical properties of the conjugated materials. Next, the inclusion of alkoxy substituents to the backbone of the conjugated polymer chain, a strategy well-known for poly(thiophene)s, is investigated in bithiazole-containing conjugated polymers. These strong electron-donating groups have been shown to largely decrease the electronic band gaps of the bithiazole polymers, and additionally have allowed for the facile preparation of these polymers through promoting the monomer’s propensity for direct arylation polymerization. Finally, the reactivity of thiazole-N-oxides is revisited in an attempt to facilitate cross-coupling with electron-rich arenes. Preliminary investigations are described in which a triflic anhydride activation strategy has allowed for the formation of 2-arylthiazoles through the nucleophilic addition of these arenes to thiazole-N-oxide.

Single-walled carbon nanotubes (SWNTs), since their first discovery in early 1990s, have drawn enormous research attention owing to their extraordinary properties. These excellent optical, electrical, thermal and mechanical properties have enabled SWNTs to make profound impacts in the field of nanotechnology, which includes nanoscale nanoelectronics, chemo-/biosensors, photovoltaics, drug delivery, and advanced nanocomposite materials. However, the as-produced SWNT samples contain a mixture of metallic and semiconducting SWNTs, amorphous carbon, and metal catalyst particles. Also, due to π-π stacking and van der Waals forces, pristine SWNTs tend to form bundles, making them insoluble in most of organic solvents. The poor processibility and purity hinder the direct use of as-produced SWNTs as the material for fabrication of SWNT-based devices. Therefore, the post-synthesis purification is highly required. Conjugated polymers have proven to be efficient SWNT dispersants, but after solution processing, conjugated polymers adhered to the sidewall of SWNTs can not be easily removed and thus negatively affect the performance of the resulting SWNT-based electronic devices. Therefore, polymers that can dissociate from the surface of SWNTs after solution processing is highly desirable. Apart from the introduction to several other efficient purification methods of SWNTs, Chapter 1 also gives a brief review on reversible functionalization of SWNTs by polymers. The work reported in the literature categorized by the different external stimuli used to reverse the polymer-SWNT association. Chapter 2 describes the design and synthesis of a vinylogous tetrathiafulvalene (TTFV)-based conjugated polymer, which is responsive to pH changes and thus realized reversible functionalization of SWNTs. Chapter 3 describes the design and synthesis of dithiafulvenyl-grafted phenylene ethynylene polymers, which can reversibly interact with SWNTs by changing solvents. Chapter 4 describes the design and synthesis of dithiafulvene (DTF)-based electron-rich conjugated polymers, which can selectively bind with semiconducting SWNTs. In addition, Chapter 5 describes the use of SEC to achieve high-resolution separation, and isolation of surfactant-free metallic and semiconducting SWNTs. This allowed us to study the competition behavior when different ratios of metallic and semiconducting nanotubes are used as the starting material for polymer dispersions. Finally, Chapter 6 describes a side project that involves covalent functionalization of GO using Piers-Rubinsztajn reaction. The functionalized GO is loaded into silicone elastomer to reduce the air permeability and enhance the mechanical strength of the resulting silicone elastomer.

▼ Conjugated polymers, though still outperformed by their inorganic counterparts, are promising materials for flexible electronics, including field-effect transistors and solar cells. The mechanical and electrical properties of this class of materials depend strongly on the morphological order. In order to design new materials and optimize existing polymers, establishing concrete links between fundamental molecular properties and structural order is necessary. As consequence, the ability to predict the properties of novel materials from their molecular structures is essential. This dissertation focuses on predicting fundamental properties and phase be- haviors of conjugated polymers from molecular structures. We develop tools and methods, combining molecular simulations and analytical theories, to predict ma- terial parameters, including the chain stiffness, the nematic coupling constant, and the Flory-Huggins χ parameter, for conjugated polymers. These fundamental parameters govern the mesoscale structures and phase behaviors for chains in melts and solutions, in turn affect the mechanical and electrical properties of conjugated polymers in the final semi-crystalline state. Using molecular dynamics (MD) simulations, we also investigate the role of thermal fluctuations in the performance of crystalline conjugated polymers. We show that thermal fluctuations can lead to cumulative lattice disorder in conjugated polymers, in turn enhance the inter-chain charge transport. Because the fluctuations of crystal shape are related to the mechanical properties of conjugated polymers, we can also obtain the elastic moduli for crystalline conjugated polymers by measuring the fluctuating box sizes in MD simulations. Altogether, this dissertation reports our progress on predicting the electrical and mechanical properties from molecular structures for conjugated polymers in both the precursor (melt and solution) and the crystalline states. Our results lay the foundation for understanding the structure-property relations of conjugated polymers in their final semicrystalline forms.

▼ Conjugated polymers consist of sequences of delocalised pi electrons along the chain backbone that impart semiconducting properties that make them useful for a range of optoelectronic applications. Using ensemble and single molecule fluorescence spectroscopy methods, this project investigates the photophysics of several conjugated polymers, with a particular focus on energy transfer processes and fluorescence intermittencies. Both confocal fluorescence single molecule methods and defocused wide-field fluorescence microscopy have been applied to characterise the emission properties of the polymers and the effects of polymer structure, molecular weight and embedding matrix investigated. The conformation of isolated chains of poly(2-methoxy-5-(2’-ethyl-hexaloxy)-1,4-phenylene vinylene) (MEH-PPV) can be controlled by changing the host matrix. In a poly(methyl methacrylate) matrix, MEH-PPV adopts a collapsed conformation and exhibits efficient energy transfer to a single, emitting site. In a polystyrene matrix the polymer exists in more elongated conformations where there is less efficient energy transfer resulting in multiple emitting chromophores from a single chain. Similarly, multiple emitting chromophores are more likely in higher molecular weight MEH-PPV. The distributions of emission behaviour in the polymers have been characterised. Fluorescence intermittencies occur on two timescales, sub-millisecond blinks are attributed to excursions to a non-emissive triplet state. Longer off times are the result of the reversible ejection of an electron into the host matrix. Limiting the chromophores in size to a five unit MEH-PPV oligomer and incorporating these chromophores as pendant groups on a polystyrene backbone results in a narrow emission spectrum but distributed photophysics. This suggests that the distribution of chromophore lengths is not the only source of fluorescence complexity in conjugated polymers, but that polymer conformation and local environment can play a significant role. Conjugated donor-acceptor block co-polymers show potential as the active material for solar cell applications. A triblock co-polymer of poly(9,9-diocetylfluorene-co-bis-N,N’-(4-methylphenyl)-bis-N,N’-phenyl-1,4-phenylenediamine) (PFM) and poly[(9,9-di-n-octylfluorenyl-2,7-diyl)-alt-(benzo[2,1,3]thiadiazol-4,8-diyl) (F8BT) was studied. It is shown that in bulk films, interactions of the PFM and F8BT blocks of adjacent chains lead to exciplex formation, although this is not observed at low concentrations in polymer matrices or solutions. An unusual delayed emission is observed in single chains of the block copolymer. It is proposed that a charge transfer state that can exist at the donor and acceptor interface leads to a delayed emission from the polymers at the bulk and single molecule level. The results of this investigation demonstrate the wide range of emission behaviours that can be observed from…

▼ Over the past 30 years conjugated polymers have demonstrated performance strides in solution-printed photovoltaics, transistors, displays, and sensors. With fundamental structure-property relationships in place, the next step is to prepare these materials for use in large-scale, high-throughput printing facilities where reproducibility, tolerance to the environment, safety, and sustainability will all play a pivotal role in the ultimate success of conjugated polymer based electronics. This dissertation explores how to achieve that next step through the use of processing components, or structural moieties that embed a desired processing property. Chapter 1 provides an introduction to the design, fundamental properties, and methods of processing soluble conjugated polymers, placing specific emphasis on the interplay between molecular structure, processability, and ultimately performance. Polymer synthesis, characterization, and processing methodology unique to this dissertation are presented in detail in Chapter 2. Chapter 3 describes the use of triphenylamine as a processing comonomer in dioxythiophene polymers. The triphenylamine comonomer templates an amorphous thin-film morphology by embedding backbone torsion and conjugation breaks, providing reproducible films that are tolerant to fluctuations in processing conditions. Chapter 4 explores the use of polymer side chains with multiple functionalities, or multistage side chains, to control solubility for aqueous printable conjugated polymers. Finally, Chapter 5 delves into the intricate morphological effects of polymer side chain placement in organic photovoltaic donor-acceptor blends. Specifically, the study utilizes a novel family of donor-acceptor polymers with methylated acceptor monomers to observe how side chain steric interactions affect morphology and optoelectronic properties in blends of polymeric donors and molecular acceptors.

▼ Conjugated polymers have been widely used in various applications including organic solar cells, electrochromic devices, chemical sensors, and biomedical devices. Poly(3,4-ethylenedioxythiophene) (PEDOT) and its derivatives have received considerable interest because of their low oxidation potential, relatively high chemical stability, and high conductivity. Electrochemical deposition is a convenient method for precisely fabricating conjugated polymer thin films. Here, we report the stability improvement and surface functionalization of electrochemically polymerized PEDOT films. The long-term performance of PEDOT coatings is limited by their relatively poor stability on various inorganic substrates. Two different methods were used to improve the stability of PEDOT coatings, one involved using carboxylic acid functionalized EDOT (EDOT-acid) as adhesion promoter. EDOT-acid molecules were chemically bonded onto activated metal oxide substrates via chemisorption. PEDOT was then polymerized onto the EDOT-acid modified substrates, forming covalently bonded coatings. An aggressive ultrasonication test confirmed the significantly improved adhesion of the PEDOT films on electrodes with EDOT-acid treatment over those without treatment. The other method was to use an octa-ProDOT-functionalized POSS derivative (POSSProDOT) as cross-linker. PEDOT copolymer films were electrochemically deposited with various concentrations of POSS-ProDOT. The optical, morphological and electrochemical properties of the copolymer films could be systematically tuned with the incorporation of POSS-ProDOT. Significantly enhanced electrochemical and mechanical stability of the copolymers were observed at intermediate levels of POSS-ProDOT content (3.1 wt%) via chronic stimulation tests. Surface functionalization of conducting polymer films provides a potential means for systematically tailoring their chemical and physical properties. We have synthesized, polymerized and characterized a dialkene-functionalized variant of the ProDOT monomer. With the alkene side groups, highly efficient post-polymerization functionalization of the conducting film was successfully achieved via a radical-based thiol-ene “click” reaction with various terminal thiols, including alkanes, ethylene glycols, and ferrocenes. These surface modification led to dramatic changes in the charge transport and wetting behavior of the chemically functionalized films. Advisors/Committee Members: Martin, David C..

▼ The effects of chain length, encapsulation and asymmetry of conjugated DPP-based polymers and small molecules were investigated. The first part of this thesis explored how chain length can affect the optical properties of conjugated DPP-based materials. Previously in our group, a series of thienyl-DPP oligomers (n = 1-5) and their polymeric counterpart were synthesised via a series of Suzuki-Miyaura cross-couplings. However, the tetramer was found to be impure. Thus, in this work the tetramer was re-synthesised via alternative reaction conditions. In addition, the DPP monomer, dimer and polymer were also re-synthesised for this study. The optical properties of the DPP oligomers were studied and it was observed that as the chain length increased from monomer to dimer, the extinction coefficient did also, at which it reached a maximum. Then, as the chain length increased from the dimer to the pentamer, the value largely decreased, suggesting that a saturation limit had been reached. On the other hand, this was challenged by the polymer’s largely red-shifted absorption compared to any other compound in the study. However, as the expected size of the red shift should decrease with extending conjugation length, this result was unexpected. It is possible that this may have been due to aggregation of the polymer chains, thus suggesting that the absorption of the DPP compounds does not rely solely on the ECL alone. The second part of this thesis explores the effect of encapsulation of the DPP core, on the performance of OPV devices. Two series of DPP-based polymers doped with an increasing amount of an encapsulated DPP monomer were synthesised, and the corresponding OPV devices were fabricated. In general, the encapsulated devices achieved higher Voc values than the reference, however the optimum amount of encapsulation was found to vary in different polymer systems. It is possible that through the introduction of the encapsulated dopant, this alters the donor-acceptor interface by either increasing the difference in the static dipole moment, reducing the ratio of the CT-state density or reducing the reorganization energy, thus resulting in an increase of the Voc. However, these results may have been affected by differences in polymer molecular weight. Three additional ring sizes of the encapsulated monomer were also investigated, followed by the synthesis of a series of encapsulated DPP-BDT based polymers. It was observed that the ring size of the encapsulated monomer had an influence over the optical properties and performance of the corresponding polymers, thus highlighting the importance of choosing the optimum ring size. The synthesis of an encapsulated and linear chained DPP-bi-thiophene co-polymer consisting of ethylene glycol side chains was also attempted, for application in bioelectronics. The final part of this thesis explores the different synthetic attempts towards a novel DPP polymer consisting of a higher DPP to thiophene ratio than previously reported. Based upon previous electronic calculations, this polymer…

▼ Conjugated polymers are active candidates of research for their potential applications in organic electronic devices. This thesis contains experimental results of the photophysical behaviour of Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) in the nanoseconds timescale. It is generally accepted that quantum yield of films are less than their solution counterparts and has a non-exponential “temporal tail” in the decay dynamics. This thesis reports the spectroscopy, excitation wavelength dependence, temperature dependence and electric field quenching of the temporal tail of the photoluminescence in MEH-PPV on a nanosecond timescale. We try to understand if a correlation exists between the “temporal tail” and quantum yield in films. We conclude that the tail represents emission from H-like aggregated regions in the polymer. Using a simple model of the photophysics, we estimate the formation yield of the aggregates responsible for the tail emission and conclude that they cannot account for the large reduction in fluorescence observed in densely packed films relative to that in solution. If recombination of injected charges in an OLED follows quantum spin statistics and all recombination forms the lowest excited states in a spin manifold, then the ratio of formed singlet to triplet exciton would be 1:3 setting an efficiency limit of 25% to the EL emission. However, in conjugated polymers, various studies have reported the formation ratio of singlet to triplet excitons to be greater than 1:3. These results have ambiguity due to issues of magnetoresistance, TTA, charge trapping, outcoupling etc. We try to reexamine the singlet-triplet branching ratio in Poly[(9,9-di-n-octylfluorenyl-2,7-diyl)-alt- (benzo [2,1,3] thiadiazol-4,8-diyl) (F8BT) along with MEH-PPV with the hope of circumventing these problems. This approach involves simultaneous detection of singlet and triplet state luminescence and then estimate the recombination branching ratios directly from the change in singlet and triplet signals produced by applying magnetic fields. The role of PP in F8BT films are addressed based on studying the effect of external magnetic field on the DF and triplet signals of gold nanoparticle doped films. This work is unique and important because it includes a delay dependent magnetic field effect study of the DF suggesting that spin randomization of charge pairs is a fast process that occurs on the several hundred nanoseconds time scale. The magnetic field effect on the fluorescence persists to tens of microseconds and we argue that this apparent inconsistency implies the existence of an intermediate state in the recombination process that has implications for measurements and theoretical treatments of the singlet recombination fraction in electroluminescent conjugated polymers.

Latently-reactive conjugated polymer-coated single-walled carbon nanotubes

Single-walled carbon nanotubes (SWNTs) are intensely investigated nanomaterials that exhibit intriguing physical and optoelectronic properties. Although SWNTs are highly regarded in terms of their potential societal impact, commercialization of SWNT applications has been dampened by the difficulty in SWNT processability and purification. Current commercially viable carbon nanotube syntheses produce complex mixtures of metallic and semiconducting SWNTs, as well as amorphous carbon and metal catalyst particles. Furthermore, the ability to decorate carbon nanotube surfaces to modulate their properties is non-trivial, especially if concurrent preservation of optoelectronic properties is desired. To date, the issues of SWNT solubilization, sorting, and functionalization have been approached in a piecemeal fashion. Conjugated polymers, which are macromolecules that possess extended π-systems, have the potential to address all of these issues simultaneously. In my Thesis, I explore conjugated polymer structures to investigate (i) factors that influence dispersion selectivity, and (ii) the decoration of polymer-SWNT complexes by incorporating reactive moieties into the polymer structure. The work presented in this Thesis begins by examining the ability of conjugated polymers to sort SWNTs. To date, the selective dispersion of metallic SWNTs is unrealized. In Chapter 2, I examine the effect of the electronic nature of the conjugated backbone on the selective dispersion of SWNTs by preparing SWNT dispersions pre- and post-methylation of a pyridine-containing conjugated polymer. In doing so, I prepare a series of polymers with identical degrees of polymerization and dispersity (to minimize extraneous selectivity factors) and find that electron rich π-systems disperse only semiconducting SWNTs, while electron poor π-systems disperse relatively more metallic SWNTs. In Chapter 3, I challenge the conventional wisdom that complete backbone conjugation is required to selectively disperse semiconducting SWNTs by introducing non-conjugated linkers into the polymer backbone and demonstrating that nanotube sorting is still possible. I next examine conjugated polymers as tools that can simultaneously sort SWNTs and impart reactivity to the polymer-SWNT complex, while preserving SWNT optoelectronic properties. In Chapter 4, I incorporate azides into polyfluorene side chains and perform solution-phase Strain-Promoted Azide-Alkyne Cycloaddition (SPAAC). I show that the polymer-SWNT complex can be rapidly decorated with strained cyclooctyne derivatives, and that only pre-clicked polymer enables for sorting of semiconducting SWNTs. The sorted SWNT population can then be made water soluble post-SPAAC, enabling for the study of SWNT emission in solvents with very different polarity. In Chapter 5, I examine the reactivity of azide-containing polymer-SWNT thin films and show that thin film properties can be drastically altered. Interfacial chemistry enables for the…

▼ In this thesis, I detail my efforts to explore organic and perovskite photovoltaic devices. Chapter 1 introduces organic photovoltaics (OPVs) and hybrid organic inorganic perovskites (HOIPs). The central challenges of working with both organic and inorganic semiconductors are discussed. Key milestones in the development of both types of devices are highlighted and the basic operating principles of general solar cells and the distinguishing features of OPVs are addressed. Chapter 2 gives a basic overview of preparing and testing OPVs and reflects on how the available systems and resources dictated how the projects described in Chapters 3 and 4 were designed and conducted. The remainder of the chapter provides an indepth description of several protocols developed to significantly improve the throughput of device testing in our lab and outlines in great detail the exact procedures used to prepare baseline perovskite devices with respectable efficiency. Chapter 3 examines the importance of bulk heterojunction morphology through the addition of insulating commodity polymers. It establishes the tolerance limits of different classes of OPVs, specifically those based on small molecule and polymer donors respectively. This study was conducted in collaboration with DuPont Canada. Chapter 4 describes my work on a series of chalcogenophene homopolymers. The study investigates how single atom substitution in conjugated polymers can be used to selectively modify properties and for the first time presents a comprehensive comparison of poly(3-alkylthiophenes), selenophenes and tellurophenes. Chapter 5 describes the development of a solution screening assay for rapidly assessing the potential utility and necessary deposition conditions of a large number of solvents for use as antisolvents in "one-step" processing of the triple-cation perovskite reported in Chapter 2. By combining solution assay results with antisolvent physical properties and diagnostic films cast on glass the selection is refined and 15 candidates are chosen for use in solar cells. Of these, six previously unreported candidates are identified and demonstrated to have promising performance in unoptimized preliminary devices. Chapter 6 summarizes the other chapters and outlines several project extensions and concepts. Advisors/Committee Members: Seferos, Dwight S, Chemistry.

▼ An in depth study of the performance of thermally interdiffused concentration gradient polymer photovoltaic devices is carried out with particular attention to the effect of the thickness and the thermal treatments on the power conversion efficiency, short circuit current, open circuit voltage and other key electrical properties. Bilayer films of sequentially spin-cast donor and acceptor materials are exposed to various heat treatments in order to induce the interdiffusion. The depth profiles show concentration gradients in the donor and acceptor as a result of interdiffusion and these devices show an order of magnitude increase in the device performance compared to the bilayer devices. Dual spin-cast poly (3-octylthiophene-2,5-diyl) (P3OT)- [6,6] phenyl C61 butyric acid methyl ester (PCBM) and poly (3-hexylthiophene-2,5-diyl) (P3HT)-PCBM interdiffused devices are studied in detail by varying the thickness of the donor and acceptor layers as well as the annealing conditions for initial polymer layer and the time and temperature of the interdiffusion process. Auger spectroscopy and X-ray photoelectron spectroscopy along with ion beam milling are used to investigate the concentration gradient formed as a result of the interdiffusion. The sulfur signal present in the P3OT and P3HT backbone is detected to identify the concentration profiles in the P3OT-PCBM and P3HT-PCBM devices. The interdiffusion conditions and thickness of the active layers have been optimized to obtain the highest power conversion efficiency. The best device performance of the P3OT-PCBM interdiffused devices is achieved when the interdiffusion is carried out at 150°C for 20 minutes and the P3OT thickness is maintained at 70 nm and the PCBM thickness at 40-50 nm. The highest efficiency achieved for P3OT-PCBM interdiffused devices is 1.0% under AM1.5G solar simulated spectrum. In order to further increase the efficiency, P3OT is replaced by (P3HT) which has higher hole mobility. P3HT- PCBM based concentration gradient devices show improved device performance over P3OT-PCBM devices. Power conversion efficiency of the order of ~3.0% is obtained for P3HT-PCBM interdiffused devices when the interdiffusion is carried out at 150°C for 20 minutes. For both P3OT:PCBM and P3HT:PCBM devices, the optimum performance occurs when the concentration gradient extends across the entire film and is correlated with an increase in the short circuit current density and fill factor as well as a decrease in the series resistance. The results demonstrate that an interdiffused bilayer fabrication approach is a novel and efficient approach for fabrication of polymer solar cell devices. In addition, porphyrin derivative 5, 10, 15, 20-Tetraphenyl-21H, 23H-porphine zinc (ZnTPP) is studied as a new donor material for organic solar cells. ZnTPP: PCBM blend devices are investigated in detail by varying the weight ratio of the donor and acceptor materials in blend devices. The devices with ZnTPP: PCBM in 1:9 ratios showed the best device performance and the efficiency of the order of… Advisors/Committee Members: Heflin, James R. (committeechair), Davis, Richey M.

▼ Photoluminescence and Resonant Raman spectroscopy were performed on the conjugated polymer MDMO-PPV (Poly[2-methoxy-5-(3\u2032,7\u2032-dimethyloctyloxy)-1,4-phenylenevinylene]), both in its pure form and in blends with electron acceptors, in order to understand how conformations are affected by interactions with neighboring polymer chains and small molecules. Thermal and solvent annealing are used to tune these interactions, and the resulting changes in the electronic structure and processes of the polymer are inferred through interpretation of spectroscopic signatures. Optical absorption and emission spectra were measured for MDMO-PPV in several solvents, in thin films processed under various conditions, and in nanoparticle form. These different environments and processing conditions can encourage the polymer to coil (bad solvent), extend (good solvent), strongly interact with neighboring molecules (nanoparticles), or interact weakly (dilute solution), and feature the polymer in a more glassy (spin-cast) or more ordered (thermally annealed) state. We can then interrogate a defind conformation of the polymer, and correlate the spectroscopic and structural changes. Analysis of the lineshape parameters of emission and absorption spectra reveal a relationship between the intensity and spacing of vibronic sidebands, and planarity of the conjugated backbone. Planarity is extremely important in conjugated polymers, as it defines the extent of electron delocalization and has serious consequences on every electronic process in the polymer. As well, solvatochromic shifts in the emission spectrum reveal information about the relative polarities of the ground and excited states. Resonant Raman spectroscopy was used to identify the vibrational modes coupled to electronic excitation, and mode-specific displacements were estimated by modeling the photoluminescence spectra using a time-dependent quantum mechanical simulation to reproduce experimental observations. Coupling of electronic processes to vibrational modes in organic photovoltaics both helps and hinders function. It broadens absorption and emission spectra, increasing the ability to absorb light and transport energy, but can provide a structural barrier to some electronic processes. However, here we use it to investigate changes in the planarity of a conjugated polymer. Spectra of polymer/C60 blend films show increased displacement of a symmetry-forbidden out-of-plane vibrational mode with increasing fullerene doping, indicating a loss of planarity. We also use photoluminescence spectroscopy to confirm this, as the electronic origin of emission blue-shifts with fullerene loading which indicates decreased conjugation length and thus molecular planarity. Ground state charge transfer complexes of MDMO-PPV and several electron acceptors were studied using linear absorption and Resonant Raman spectroscopy to better understand the nuclear rearrangements that the polymer undergoes upon loss of an electron. Any bonds displaced upon the movement of charge will make it… Advisors/Committee Members: Grey, John, Qin, Yang, Malloy, Kevin, Dunlap, David.

▼ Redox active conjugated polymers are used in a variety of applications including electrochromism, charge storage, plasmonic resonance tuning, and electrochemical transistors. This thesis describes the development of processable, electron-rich dioxyheterocycle-based polymers for use in electrochromic and charge-storage applications. This thesis reports the development of soluble polymers that can be solution processed from organic or aqueous solutions (inks) and are redox active in organic or aqueous electrolytes with variable optical and redox properties through subtle differences in the repeat units and heteroatoms used. This thesis describes the development of processable, electron-rich dioxyheterocycle-based polymers for use in electrochromic and charge-storage applications. Materials with low onsets of oxidation and broad electroactivity over a large voltage window, as seen with electropolymerized poly(3,4-ethylenedioxythiophene) (PEDOT), are of interest for charge storage applications. Chapter 3 reports and discusses the copolymerization of alkoxy-functionalized 3,4-propylenedioxythiophenes (ProDOTs) with unfunctionalized 3,4-ethylenedioxythiophene (EDOT) in varying ratios using direct arylation to produce a series of solution processable polymers with highly tunable optical and electronic properties. Within this series, we have identified poly(ProDOT-alt-biEDOT) (PE2), a copolymer containing 67% EDOT compositionally, which combines the low oxidation potential, the redox behavior, and the deep-blue neutral color that are characteristic of PEDOT with the high solubility, exceptional electrochromic contrast, and color neutrality in the oxidized state characteristic of alkoxy-functionalized polyProDOTs. 3,4-Phenylenedioxythiophene (PheDOT) is a unit that is similar to EDOT in terms of planarity and steric interactions but has different electronic properties due to an attached phenyl ring that allows for electron delocalization away from the thiophene ring. This unit, and its use in soluble copolymers prepared via direct (hetero) arylation polymerization (DHAP), is discussed in Chapter 4. The notable C-H inactivity of the attached phenylene unit is compared to aromatic solvents used for DHAP and the redox stability of these copolymers are demonstrated. The first example of a solution processable dioxythiophene-alt-dioxyselenophene polymer, poly(ProDOT-alt-EDOS), prepared via DHAP is reported and its optical and electrochemical properties are compared to the all thiophene analog and other relevant dioxythiophene polymers. By substituting the sulfur atom for a selenium atom on one of the monomers in the repeat unit, a significant red-shift of both the neutral and polaronic absorbances results, as well as a reduction in the onset of oxidation compared to the all thiophene analog.Due to the redox and optical similarities of PE2 and PEDOT, the solid-state electrical conductivity of the chemically doped ProDOTxEDOTy series (discussed in Chapter 3) is studied in Chapter 6. Additional polymer structures are introduced to… Advisors/Committee Members: Reynolds, John R. (advisor), Marder, Seth R.

▼ Redox-active conjugated polymers have been investigated for a multitude of applications including electrochromic displays, transistors, and transparent conducting electrodes. As with all fields of polymer science, the material properties observed for these conjugated polymers are determined by their structure. While the groundwork for probing their fundamental structure-property relationships has been established, there is still much to be explored in order to have a holistic understanding of these systems. This dissertation aims to investigate how the structure of dioxythiophene polymers can affect the processes of chemical and electrochemical oxidation, their charge transport properties, and their use in electrochemical and solid-state applications. Chapter 1 provides an introduction to the fundamental properties and concepts of conjugated polymers, and their use in potential applications. Characterization methods used in this work, including electrochemical experimentation and dry-film characterizations are highlighted in Chapter 2. Chapter 3 describes the work exploring how the use of chemical oxidants and phosphonic acids can be used as pre-treatment steps in the construction of electrochemical devices. A family of polymers including two dixoythiophenes (DOTs) and one dioxypyrrole (DOP) were exposed to a series of chemical oxidant salts with the oxidizing agent either being Ag+ or Fe3+. The structure and redox properties of the conjugated polymers were shown to affect the overall extent of oxidation. Specifically, the DOT polymer that had the highest onset of oxidation in the family was oxidized to a lesser extent when using Ag+ as the chemical oxidant rather than Fe3+. In contrast, the DOT polymer with the lowest onset of oxidation in the family was oxidized to the same extent using both dopants. Using Fe3+ was shown to disrupt the interface between films of each polymer in the family and the conducting substrate, however this was rectified through modification of the surface energy of the substrate using phosphonic acids. Ultimately, it was shown that devices constructed after chemical pre-oxidation had comparable electrochromic contrasts to those using an electrochemical pre-oxidation step. Chapter 4 explores the effects of side chain alteration on the charge transport properties of a family of either 3,4-propylenedioxythiophene (ProDOT) or acyclic dioxythiophene (AcDOT) homopolymers. It was shown that the incorporation of linear side chains rather than branched side chains for both the ProDOT and AcDOT polymers allowed for a decrease in the onset of electrochemical oxidation by 300 mV and a 2 order of magnitude increase in the solid-state in-plane conductivity (10-3 vs 10-1 S/cm) after chemical oxidation. This study ultimately showed that there is a delicate balance in the degree of ordering of the polymer film and effective charge transport. Chapter 5 further supported this concept of balance by probing a family of soluble dioxythienothiophene (DOTT) polymers for their structure-property relationships.… Advisors/Committee Members: Reynolds, John (advisor), Bottomley, Lawrence (advisor), Collard, David (advisor), Silva, Carlos (advisor), Lin, Zhiqun (advisor).

▼ Quick and early detection of abnormalities in the body's metabolism is of paramount importance to monitor, control, and prevent the associated diseases and pathologies. Biosensors technology is rapidly advancing, from the first electronic biosensor reported by Clark and Lyons in 1962 for blood glucose monitoring to today’s devices that can detect multiple metabolites in bodily fluids continuously and simultaneously within seconds. This rapid growth in point-of-care devices promises for the development of novel devices with different form factors and the ability to detect a wide range of biomarkers. These advancements mainly stem from the development of electronic materials that have properties better aligning with the biotic interface compared to the traditional metal electrodes. A promising class of electronic materials for biosensors is conjugated polymers. Conjugated polymers are carbon-based, organic semiconducting materials made of long chains comprising conjugated repeat units. The fundamental property that makes these materials so attractive is, however, not their electronic conductivity, but their ionic conductivity. As living organisms use ionic fluxes to relay signals, materials that can conduct ionic currents are believed to facilitate the communication between the electronics and living systems. This communication happens at various levels: organs, complex tissues, cells, cell membrane, proteins, and small biomolecules. Besides, the inherently soft nature of these materials facilitates mechanical conformity with soft biological systems. The field of organic bioelectronics has experienced tremendous growth over the past two decades, thanks to the design of new conjugated polymers customized for the biotic interface. While hole conducting (p-type) polymers have been widely investigated, electron conducting (n-type) counterparts are relatively new. This dissertation aims to explore the capabilities of n-type conjugated polymers for bioelectronics applications. Chapter 1 overviews the key properties of conjugated polymers and the resulting electronic devices that leverage these properties for specific applications in bioelectronics. Chapter 2 presents microfabricated metabolite (lactate and glucose) sensors based on an n-type polymer in combination with enzymes, and how this communication can enable energy production from bodily fluids. Finally, Chapter 3 reports the development of engineering and design strategies to enhance the performances of n-type polymers in bioelectronics.

▼ The olefin metathesis reaction has become one of the most powerful carbon-carbon bond forming reaction in synthetic chemistry. This work has expanded the utility of olefin metathesis in metal coordination spheres in three major directions (1) the synthesis and characterization of trans-spanning bis(pyridine)PtCl2 complexes, (2) the developme-adducts of polyacetylene (PA), and (3) the development of regioregular -adducts of poly(phenylene-vinylene) (PPV). Chapter I gives a brief overview of olefin metathesis and previous applications to organometallic substrates. Chapter II details the synthesis of pyridine ligands containing alkenyl substituents, 2-NC5H4(CH2O(CH2)nCH=CH2) (n = 1, 2), 3-NC5H4(CH2O(CH2)nCH=CH2) (n = 1-5, 8, 9), and 3,5-NC5H3(p-C6H4O(CH2)7CH=CH2)2. Metalation of the new ligands with PtCl2 affords the corresponding trans-bis(pyridine)dichloroplatinum complexes, trans-PtCl2(2-NC5H4(CH2O(CH2)nCH=CH2))2 (n = 1, 2), trans-PtCl2(3-NC5H4(CH2O(CH2)nCH=CH2))2 (n = 1-5, 8, 9), and trans-PtCl2(3,5-NC5H3(p-C6H4O(CH2)7CH=CH2))2. Ring-closing metathesefirst generation catalyst followed by hydrogenations with Pd/C afford the title complexes trans-PtCl2-(NC5H4(CH2O(CH2)2n+2OCH2)H4C5N)] (n = 1, 2), trans-PtCl2-(NC5H4(CH2O(CH2)2n+2OCH2)H4C5N)] (n = 4, 8, 9), and trans-PtCl2-(NC5H3(p-C6H4O(CH2)12O-p-C6H4)2H3C5N)]. Reactions with methylmagnesium bromide afford trans-PtCl(CH3)(3-NC5H4(CH2O(CH2)nCH=CH2))2 (n = 2, 8) and trans-PtCl(CH3-(NC5H4(CH2O(CH2)nOCH2)H4C5N)] (n = 10, 18), which feature dipolar rotators. Low temperature NMR spectra in the latter remained facile on the NMR time scale in CDFCl2 at -120 degrees Celsius. Chapter III focuses on the application of ROMP with organometallic monomers to form metal pi-adducts of polyacetylene. The new complex (n4-benzene)Cp*Ir has been synthesized, crystallographically characterized, and evaluated in the ROMP reaction. Monomers (n4-benzene)CpIr, [(n6-COT)CpRu][PF6], and (n4-COT)Fe(CO)3 were also evaluated in the ROMP reaction. ROMP of (?4-benzene)CpIr with Grubbs' first generation catalyst afforded the conductive regioregular polymer CpIr-PA. Chapter IV focuses on the synthesis of the divinyl benzene complexes [Cp*Ir(C6H4(CH=CH2)2)][BF4]2 and [Cp*Ru(C6H4(CH=CH2)2)][OTf] and their polymerization via ADMET to afford PPV systems. Treatment of divinyl benzene ed the conductive regioregular polymers [Cp*Ir-PPV][BF4]2n and [Cp*Ru-PPV][OTf]n. The photophysical properties of the new -metal adducts of PPV exhibit blue-shifts relative to typical PPVs and retain strong UV absorption. Advisors/Committee Members: Gladysz, John A.
