▼ CO2 functionalization to commodity chemicals and molecular energy provide an powerful mechanism to leverage one of the world most abundant alternative sustainable carbon resources. This work focuses on the development of inexpensive earth abundant iron and molybdenum catalysts for the reduction CO2 toward two key commodity chemical targets: acrylate and formate. NaEt3BH reduction of (Triphos)MoCl3 afforded novel molybdenum tetrahydride species (Triphos)MoH4PPh3, which was found to promote CO2 functionalization to afford acrylate, propionate and formate species. Mechanistic study permitted control of the selective to the CO2-ethylene coupling product. Methods of acrylate elimination from the molybdenum center were also explored including the use of external bases and exogenous ligands. Strong bases and strong ligands such as CO or tBuNC, were found to induce acrylate elimination along with concomitant generation of acrylates and zero-valent molybdenum species. The reductive acrylate elimination studies may open pathways for catalytic acrylate generation. The nature of ancillary ligand flexibility on CO2-ethylene coupling at molybdenum complexes was probed by comparative reactivity of two PNP pincer ligands. The first isolable zero-valent (PhPNpyP)Mo(C2H4)2(CO2) exhibited no acrylate formation despite having the requisite components coordinate to the metal. Alternative and more flexible complexes, (PhPNagostic-CH3P)Mo0(C2H4)2 and (PhPNCH2P)Mo(H)(C2H4)2, were also studied. CO2 insertion into the Mo-H bond of (PhPNCH2P)Mo(H)(C2H4)2 produced (PhPNCH2P)Mo(C2H4)(κ2-CHO2), which proved a modest and rare catalyst for CO2 hydrogenation to formate with assistance of Lewis acid (LA). Further development of catalysts for CO2 reduction to formate pursued iron(II) carbonyl hydride complexes supported by either a bifunctional PNP ligand containing a secondary amine, or a PNP ligand with a tertiary amine that prevents metal-ligand cooperativity. Both of these species were found to promote the catalytic hydrogenation of CO2 to formate in the presence of Brønsted base. A remarkable enhancement in catalytic activity was observed upon addition of LA co-catalyst in both cases. For the secondary amine supported system, TON of approximately 9,000 for formate production was achieved, while for catalysts supported by the tertiary amine ligand, nearly 60,000 turnovers were observed; the highest activity reported for an earth abundant catalyst to date.

▼ Binding molecular groups and nanoparticles on graphene and hexagonal boron nitride (h-BN) will expand their applications scope by offering sites to interface with other material systems. However, such functionalization makes it challenging to retain the trigonal sp2 hybridized lattice. The conventional modification routes for graphene are “carbon-centered” that change its local hybridization of carbon atoms from sp2 to tetrahedral sp3. This disrupts the lattice planarity of graphene, thus dramatically deteriorating its innate superior properties. The low intensity of defect-induced peak (D-band) in Raman spectroscopy and slight change in carrier-mobility from electronic measurements after η6-functionalization strongly proved that graphene’s planar lattice and high carrier-mobility were retained. The grafted chromium carbonyl (Cr(CO)3) groups further acted as reactive sites for silver nanoparticles (AgNPs)’ nucleation and growth. The AgNPs attached on η6-graphene were applied as plasmonic centers in Schottky junction solar cells, improving power conversion efficiency by 11-times. Based on the η6-chemistry, transition metal oxide nanoparticles (TMONs, CrxO3, MoO3 and WO3) were successfully incorporated on graphene via a one-step, photo-organometallic route. Specially, a bracelet-shape CrxO3 nanoparticles were deposited on graphene only at room temperature via dipole-directed self-assembly. The slight change of D-band intensity showed that graphene’s sp2 structure has been retained after the attachment of TMONs. The Fermi level of graphene was reduced by 250 mV with enhanced conductivity and only one order of magnitude reduced in carrier mobility. As an analogy of graphene, h-BN also has π-electrons at the interplane sheets, which are essential for organometallic, ring-centered modification. The Cr(CO)3 moieties are bonded to hexagon rings of h-BN’s basal plane, overcoming the challenge that chemistries only occur at edges and defect points in transitional functionalization. A downshift of E2g-phonon mode by about ~4 cm-1 with a reduction of optical band gap was achieved in η6-h-BN. Graphene grain boundaries (GB) are formed while two grains coalesce together, which are more active for chemical reactions. By bonding with pentagon-rings, a technique to selectively modify graphene at GB regions is proposed. The doping effect η5-chemistry enhanced the D-band signal at GB regions with reduced carrier-mobility. Advisors/Committee Members: Berry, Vikas (advisor), Takoudis, Christos G.

▼ BODIPY, also known as “porphyrin’s little sister,” belongs to a class of fluorescent dyes. It contains a dipyrromethene π-system with a disubstituted boron atom. The basic 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) is known for its numerous useful applications in the fields of biology and materials. Modification of this well-known fluorophore has been shown to change its photophysical and chemical properties. There has been great interest in the modification at the boron center in recent years for synthesizing new dyads and cascade-type dyes. This work focuses on functionalization at the boron center with carbon and oxygen nucleophiles for further investigation as bioimaging agents. Chapter 1 of this dissertation describes an overview of BODIPYs including synthetic development, post-synthetic functionalization strategies, and how BODIPYs can be involved in many biological applications. Chapter 2 discusses the synthesis, characterization, and computational studies of 4,4-dialkoxy BODIPY and its derivatives. Preliminary studies with various Lewis acids and alcohols will be investigated and discussed. In collaboration with Dr. Petia Bobadova-Parvanova of Rockhurst University, the photophysical properties were studied using computational analysis. The structural, spectroscopic and fluorescence properties of all the synthesized BODIPYs will be studied and be compared. Chapter 3 presents the synthesis and characterization of 4,4’-dicyano-BODIPYs. A novel route for preparation of 4,4’-difunctionalized BODIPYs bearing phenyl and various substituents at the boron center was developed. These compounds were synthesized in a three step one-pot reaction between dipyrromethenes and dichlorophenylborane, followed by replacement of chloride with fluoride and various carbon- and oxygen-centered nucleophiles. These BODIPYs’ structural, spectroscopic, and fluorescence properties are reported and discussed. Chapter 4 represents the investigation of six 1,2,3-triazole-BODIPYs under the Cu(I)-catalyzed Huisgen cycloaddition reaction conditions. A novel BODIPY bearing a chiral moiety was synthesized using method C and X-ray crystallography confirmed its identity. Chapter 5 reports the synthesis of chloroalcohol compounds via triphosgene-triethylamine activation. An asymmetric SN1 reaction was investigated through the use of an oxazolidinone.

▼ In this project, the synthesis of carbon encapsulated copper nanoparticles using sustainable bioproducts as raw material was systematically studied. The synthesis mechanism, process parameters, and functionalization of carbon encapsulated copper nanoparticles were well established. In a preliminary study, carbon encapsulated copper nanoparticles were successfully synthesized at 1000 ºC, 1h, 20 ºC/min, and 1800 sccm argon gas flow rate using BCL-DI lignin as the carbon source. Carbon encapsulated copper nanoparticles were mainly located at defect sites. Copper was found not tightly encapsulated by graphene shells. The carbon encapsulated copper nanoparticles were uniformly distributed. The conversion of copper ions into copper atoms occurred at above 300 ºC, with the company of decomposition of BCL-DI lignin into CO, CO2, and hydrocarbon gases. The growth of graphene layers was proposed to start above 300 ºC. TEM images illustrated the onset of growth of graphene at the edge of the surface at 400 ºC, and the formation of graphene bands at 500 ºC. Copper catalyst continued to facilitate the decomposition of lignin functional groups at 600 ºC. Further increasing the temperature retarded the degradation of lignin, while assisted the reconstruction of the defective sites of the graphene layers, producing higher quality products. Plastic film phase of lignin dominated on the synthesis of carbon encapsulated copper nanoparticles, while gaseous phase had little impact. The orthogonal experiment revealed that temperature played the most important role in the growth of graphene: high temperature was preferred in order to obtain less defective sites. The optimum synthesis parameters were suggested as 1000 °C, 30 min duration time, 20 °C/min temperature rising ramp, and 1200 sccm argon gas flow rate. Post heat treatment was proved to be a feasible way to improve the crystallinity of graphite. Amorphous carbon was removed or converted into crystalline graphite under heat and oxygen. FTIR spectra confirmed the covalent linkages between carbon encapsulated copper nanoparticles and N-methyl-2-pyrrolidone and polyvinylpyrrolidone, indicating a successful functionalization. This study has presented a homogeneous carbon encapsulated copper nanoparticles solution in water and ethanol, and paved ways for further functionalization of CECNs. Advisors/Committee Members: H. Michael Barnes (chair), Jilei Zhang (chair), El Barbary M. Hassan (committee member), Dragica Jeremic Nikolic (committee member).

▼ Engineered nanomaterials (NMs), tiny synthetic materials having at least one dimension between one and one hundred billionths of a metre, are increasingly being developed for and incorporated into a myriad of commercial, consumer, and industrial applications due to their unique and tailorable properties. Widespread and expanding production and use of engineered NMs implies that they will enter aquatic environments through accidental (e.g. down-the-drain disposal of NM-containing consumer products) or intentional (e.g. groundwater remediation efforts) anthropogenic release and thus have the potential to interact with and adversely affect living organisms like fishes. My research aimed to identify the physical and chemical properties intrinsic to the NMs themselves (e.g. surface coatings or functional groups) and extrinsic environmental factors (e.g. solar radiation) that modulate NM toxicity using fish model systems. Several functionalized and nonfunctionalized metal oxide and carbon-based NMs were characterized using appropriate analytical instruments and techniques. The information derived from these studies was used to better understand the interactions between NMs and biological systems and to accurately evaluate and interpret the toxicological effects resulting from exposure. Zebrafish (Danio rerio) embryos were exposed to a range of NM concentrations (0.1 2000 mg/L) under laboratory and more environmentally realistic conditions for up to seven days, multiple endpoints indicative of toxicity (e.g. alterations in gene expression, delayed development, incidences of malformation, increased antioxidant enzyme activity, lethality, lipid peroxidation, etc.) were assessed, and the potential mechanisms underlying noted toxicity were elucidated. Moreover, a combination of flow cytometry and laser scanning confocal microscopy was used to investigate the cellular uptake mechanisms of NMs and to determine their subsequent fate within rainbow trout (Oncorhynchus mykiss) gill epithelial cells. The work presented here represents the first comprehensive, explicit, and systematic evidence-based report on the toxicology of functionalized NMs in fishes and some of the major findings were as follows. Most NMs adsorbed to or settled on the embryonic zebrafish while some traversed the chorion and sorbed to the developing fish within the chorionic membrane. However, the NMs located on the external larval surface could not be distinguished from those that may have been internalized by the animal using in vivo methods. Further in vitro measurements demonstrated that these surface bound NMs were actively taken up into rainbow trout gill epithelial cells via clathrin mediated endocytosis and became localized within lysosomal compartments. Surface functionalization was found to affect the characteristics of certain carbon based NMs resulting in differential responses and thus played a key role in determining their toxicity at different levels of biological organization. Furthermore, the surface coating was shown to lessen the severity of…

▼ Carbon nanotubes (CNTs) and graphene are dominant and emerging carbon-based materials that have attracted extensive attention for potential applications in advanced nanotechnology. The attractiveness of these materials originates from their excellent mechanical, thermal, and electrical properties. However, their insolubility and difficult processability in solvents have significantly limited their use. To solve these problems, surface functionalization is used to increase their solubility, enhance their processability in solvents, and integrate these materials into nanodevices. Conventional methods are being challenged due to their ineffective and insufficient control of the functionalization of CNTs or graphene, which is critical to realize tailored structures with unprecedented optical, electrical and catalytic properties. Further development in this field requires a fundamental understanding of the steps involved in surface functionalization, namely the reaction mechanism(s) and controlled kinetics, to yield tailored structures. The overall objective of my dissertation is to develop new approaches to functionalizing CNTs and graphene, study the functionalization mechanism and kinetics, and fabricate tailored structures with unprecedented properties. The study begins with developing new covalent functionalization methods for CNTs and graphene based on the defect chemistry method. This method is less destructive and more reactive compared to the conjugate structure method. Amination of MWCNTs with octadecylamine on the mutual position of pyracyclene units in the closed caps and pentagons on the MWCNT sidewalls is developed. The functionalized MWCNTs possess controllable surface wettability. For covalent functionalization of GO, dual-function silane agents were reacted with GO through oxygen containing groups. The exposed amine groups of the functionalized GO could effectively template the assembly of Au nanoparticles on the graphene surface with high density and good dispersity. The GO-Au composites exhibit improved surface-enhanced Raman scattering and enhanced efficiency in catalytic applications. For the noncovalent method, ZnO-CNT and ZnO-GO composites were prepared. Due to the electronegative nature of CNTs and GO, ZnO nanoparticles with positive charges can anchor on their surfaces through electrostatic attraction. The creative combination of CNTs or graphene and ZnO leads to higher efficiency and stability for photocatalytic applications than the corresponding components, which makes them a new class of functional materials to advance nanotechnology.

▼ Introduction: Nanoparticles (NPs) are gaining increased popularity for cancer treatment, especially the multifunctional nanoparticles like Quantum dots (QDs) which have a wide range of applications in nanotheranostics, cell imaging and targeted drug delivery to cancerous tissue. QDs comprise of very tiny crystals of a semiconductor material (diameter: 2-10 nm) capable of producing bright, intensive and size-tuneable near-infrared fluorescence emissions. In particular, 3-mercaptopropionic acid -capped Cadmium Telluride Quantum Dots with a zinc sulphide shell (MPA-capped CdTe/ZnS QDs), are known to be very stable, highly photoluminescent, less toxic with long-lasting “fluorophore” effects, thus making them the preferred QDs for this study. Aims: To synthesize and characterize biocompatible MPA-capped CdTe/ZnS QDs to determine size range, polydispersity index (PdI), zeta (ζ) potential, photoluminescence (PL) spectra, stability in various milieus as well as to evaluate the effects of the synthesized QDs on the viability and morphology of neuroblastoma (NB) and glioblastoma (GB) cell lines using the WST-1 cell viability assay, imaging and cell cycle analysis. Materials and methods: MPA-capped CdTe/ZnS QDs were synthesized and analysed with the Zetasizer to determine ζ-potential, hydrodynamic (hd) size and PdI, while high resolutiontransmission electron microscopy (HR-TEM) was used to validate the hd size and elemental composition using energy dispersive X-ray (EDX) spectra. Pl absorption and emission spectra were obtained with a fluorometer and stability studies were done using UV-Vis spectroscopy, permitting further biological evaluation. A concentration range of 5-20μg/ml QDs was exposed to U87 and SH-SY5Y cancer cell lines to determine biological effects at different time points, using the WST-1 assay. Confocal fluorescence microscopy was used to establish uptake and cellular localization of the QDs, cell morphology was visualized with an inverted microscope while cell cycle distribution analysis was done using the C6 flow cytometer.

In nature, many organisms have the ability to adapt and change their structural configuration at the nanoscopic level, providing them an exquisite variety of properties and dynamic interactions with their environment. Mimicking such complex systems would open the path towards such properties and interactions. However the investigation of such systems requires first to understand and control the self-assembly of nanostructured systems and next to understand and control the reconfiguration mechanisms. This thesis aims at addressing the first part of this objective. Based on a "bottom-up" approach, the objectives of this work are the design, the manufacture and the characterization of self-assemblies of (multi)functionalized nano-building blocks. These self-assemblies should be thin films presenting an ordered structure at a scale close to the one of the building blocks ("supra-crystalline") dependent on the system conditions, such as the pH or the temperature. The nano-building blocks chosen here are functionalized nanowires (NWs) made of noble metals (Pt, Au or Pd). They were synthesized by electro-chemical deposition in nanoporous membranes. This templating method simultaneously allowed to chemically modify specific parts of the NW surface, especially their bases. The chemical functionalization was achieved using either thiol assembly or polyelectrolyte adsorption. Homogeneously functionalized as well as homogeneously multi-functionalized NWs were obtained. The NWs were then assembled using two different methods: drop-casting on functionalized substrates and assembly at the toluene-water interface. For the latter method, different techniques (fishing, drain-to-deposit or PDMS stamp inking) were tested to recover the assemblies on appropriate substrates, allowing their characterization by SEM or AFM. The influence of several parameters such as the nature of the nano-object, the functionalization of the nano-objects or substrate, the pH, etc. on the compactness (density) and organization of the assemblies was studied.

▼ The modular electronic and steric properties of iron dipyrromethene complexes were explored to facilitate electronic structure investigations via intermediate isolation and catalyst design for controlled C–H amination processes. To this end, a sterically accessible tert-butyl substituted dipyrrin (tBuL = 1,9-di-tert-butyl-5-(2,6-dichlorophenyl)-dipyrromethene) scaffold allowed for identification of a terminal iron iminyl (tBuL)FeCl(•NC6H3-2,6-iPr2). Akin to the previously reported (ArL)FeCl(•NC6H4-4-tBu) (Ar = 2,4,6-Ph3-C6H2), this species is best described as a high-spin FeIII center antiferromagnetically coupled to an iminyl radical. These results establish the inherent preference of the dipyrrinato iron platforms for such a unique electronic construct which serves to render the iron iminyl species highly reactive and yet stabilize it to permit its direct isolation in the absence of a protective scaffold. Removal of the ortho aryl substituents, however, promotes formation of a di-iron bridging imido [(tBuL)FeCl]2(μ-NC6H3-3,5-(CF3)2) displaying two antiferromagnetically coupled high-spin ferric centers. This complex can successfully transfer the N-group into styrene as well as allylic and benzylic C–H bonds under stoichiometric and catalytic conditions. Both dissociation into an iron iminyl and an unprecedented direct hydrogen atom abstraction (HAA) at the dinuclear imide are viable routes for the C–H amination process, demonstrating the importance of an open-shell electronic configuration to promote reactivity at such otherwise inert dimeric motifs. With a broader understanding of the electronic features of the iron dipyrrin system, systematic tuning of ancillary anionic ligands enabled the development of a diastereoselective C–H amination synthesis for 2,5-disubstituted pyrrolidines from linear alkyl azides following a previously reported protocol in our group. A combination of experimental observations and theoretical investigations provided insight into the selectivity determining HAA transition state to recognize the steric clashes between the azide substrate and the catalyst that disfavor a trans arrangement of the 2,5-substituents. Building upon these interactions, among a series of alkoxide and phenoxide complexes surveyed, (AdL)Fe(OPh)(THF) was found to induce high diastereocontrol (> 20:1) for a range of 1-azido-1-aryl-hex-5-ene substrates. Attempts to expand the synthetic viability of these iron complexes led to the unexpected discovery of dipyrrinato iron tetrazenes as highly active catalysts for the intramolecular C–H amination transformation. 57Fe Mӧssbauer, kinetic and NMR studies corroborate the direct participation of these robust and rather sterically encumbered iron tetrazenes during catalytic turnover. Both electronic and steric effects were identified as contributors for the different reaction rates observed for a series of alkyl and aryl substituted tetrazene moieties. Overall, these systems manifest remarkable stability during catalysis, can operate at catalyst loadings as low… Advisors/Committee Members: Nocera, Daniel (advisor).

▼ Transition metal-catalyzed functionalization of C-H bonds has been used as a powerful tool for the construction of C-C and C-heteroatom bonds. Within this dissertation, methods that allow functionalization of C-H bonds via iron and copper catalysis have been developed. Additionally, functionalization of sp3 C-H bonds in amino acid derivatives using auxiliary-assisted palladium-catalyzed methodology is also demonstrated. A method for iron-catalyzed alkylation of arenes and heterocycles containing acidic C-H bonds has been developed. Various heterocycles such as pyridine, furan, thiophene and electron deficient arenes can be coupled with both alkyl bromides and iodides. Magnesium amide base is required for the reaction. Similarly, the deprotonative dimerization of arenes and heterocycles can be effected in the presence of an iron catalyst. Thus, the method allows direct functionalization of arenes and heterocycles. Additionally, the use of an iron catalyst is an advantage compared with existing methods. Methods for copper-catalyzed direct sulfenylation and amination of sp2 C-H bonds have been developed. Using 8-aminoquinoline auxiliary and copper catalyst, ortho C-H bonds of benzoic acid amides can be sulfenylated by disulfides. The method provides an alternative, milder way for the preparation of aryl trifluoromethylsulfides. Furthermore, ortho C-H bonds of benzoic acid amides can be aminated by reaction with simple amines using 8-aminoquinoline directing group and a copper catalyst. Sulfenylation and amination of -C-H bonds of benzyl amine derivatives using picolinic acid auxiliary were also demonstrated. Broad substrate scope, high regioselectivity, and good functional group tolerance were observed. The use of a copper catalyst and a removable directing group are significant improvements compared with the existing methods. Finally, a novel way for synthesis of non-natural amino acids via auxiliary-assisted, palladium-catalyzed C-H functionalization methodology was developed. Under palladium catalysis, 2-methyl thioaniline auxiliary allows the monoarylation of -C-H bonds of alanine derivatives generating, after directing group removal, substituted phenylalanines. In contrast, using 8-aminoquinoline auxiliary, methylene groups in phenylalanine, leucine, and lysine derivatives can be arylated. Methods for alkylation and acetoxylation were also reported. The directing group can be removed without significant erosion of enantiomeric excess. The method provides a straight-forward way to synthesize non-natural amino acids from the chiral pool.

▼ The thesis presented here describes methodologies to produce pendant group functionalized polyesters from amido-functionalized Î±-hydroxy acids. The synthetic methods used to produce the functionalized Î±-hydroxy acids are compatible with a wide array of functional groups, making this technique highly versatile. The synthesis of functionalized polyesters was investigated to develop polymers with properties that may improve the capabilities of existing biodegradable polyesters for applications in controlled release pharmaceuticals. Chemically modified a-hydroxy acids were synthesized by reacting glyoxylic acid with a primary or secondary amide. To demonstrate the utility of this reaction, fourstructurally dissimilar amide substituents were examined including 2-pyrrolidione, benzamide, acetamide and acrylamide. The reaction is synthetically simple, provides high yields and is uniquely flexible, functionalized monomer. The compatibility of this procedure with the collection of functional groups mentioned circumvents the need for syntheses. The amido-functionalized monomers were polymerized by two different techniques: melt polycondensation and solution polymerization. Melt polycondensation was conducted by heating the monomer past its melting temperature under reduced pressure. Oligomeric functionalized polyesters (= 800 g/mol) with low PDIs (= 1.05) were obtained by melt polycondensation. Melt polycondensation was not compatible with all of the synthesized monomers. Two of the monomers (containing benzamide and acrylamide functionalities) degraded before the polycondensation reaction occurred. Thermal gravimetric analysis confirmed that a process other than polyesterification was occurring, indicating that some amido-functionalized Î±-hydroxy acids cannot be synthesized in the melt.Solution polymerization was conducted to polymerize functionalized Î±-hydroxy acids that were incompatible with melt polycondensation. Several modified Steglich polyesterifications were tested including p-toluenesulfonic acid mediated and scandium (III) triflate catalyzed. Only oligomeric functionalized polyesters were formed bythis method. A number of possible side reactions including the formation of an N-acylurea and a cyclic polymer ring were possible. The utility of this procedure appears to be limited due to the complexity of the reaction and its inability to produce high molecular weight polymer.

▼ Functionalization of nanomaterials is a definitive strategy to modulate them to achieve desired properties. Any functionalization introduces defects in the 2D lattice, which affect the properties of these layered materials. This thesis focuses on the effects of fluorination on the structure and properties of atomically thin-layered materials and a variety of applications of these materials in the fields from medicine to energy will be covered in this thesis. The first chapter gives an overview of nanomaterials in general, focusing more on 2D materials, their functionalization and their unique properties. To tailor to the rest of the chapters, a brief discussion about fluorinated graphene - the strategies of fluorination developed, their advantages and limitations; the structural defects introduced by fluorination and its influence on the conversion of a zero-bandgap material to a semi-conductor and the collective magnetism induced by point defects is discussed. The second chapter talks about fluoro-graphene quantum dots focusing on my work and its application in MRI and why it could potentially push the limits of MRI. FGO being a metal free agent has less contrast compared to conventional agents. Therefore, the third chapter gives a perspective on the enhancement of MRI contrast by formation of FGO-Iron oxide composite, as well as using it as utilizing the fluorescence of FGO in cellular imaging. The fourth chapter opens with the motivation from structural and functional changes in fluoro-graphene to explore fluorine functionalization in other 2D materials like h-BN, MoS2 and WS2. The new technique developed for functionalization will be compared with the existing techniques discussed in the first chapter, and point out the advantages of the method in terms of scalability, controllability etc. The modification of electronic band structure of h-BN to a wide bandgap semiconductor via introduction of defect levels will be described in detail along with the band structure calculations using DFT. An analysis of the origin of unconventional magnetic behavior induced by fluorination and room temperature ferromagnetism will be followed by its application as a magnetic semiconductor. The fifth chapter would be an extension of the fourth chapter, a discussion of the optical properties of FBN quantum dots and its modulation with the amount of fluorination will be followed by its application in biological detection. Moving on to the sixth chapter, it explores the effect of fluorination on other 2D materials like WS2 and its consequent exfoliation and transformation. With an interest in the changes in tribological properties of TMDs like WS2 with doping and gating this chapter will also study the measurement of friction in f-WS2 using AFM. The chapter closes with a study on the magnetic properties. The seventh chapter summarizes the main findings of the thesis and reviews the scope for further studies.

▼ For decades, synthetic organic chemists have constructed organic molecules by manipulating functionality already existing on the scaffold. Simple chemical feedstocks, typically derived from petroleum, are pre-installed with oxidized moieties, which can then undergo a series of transformations known as functional group manipulations to build up molecular complexity. Recently, a different approach has emerged wherein inert and ubiquitous C—H bonds in organic molecules can be specifically targeted for chemical transformations, obviating the need for preexisting functional groups. However, this approach confronts organic chemists with an inherent and paradoxical challenge of developing reagents and catalysts that are reactive enough to cleave these strong and inert C—H bonds, while still being able to functionalize in a selective and predictable manner. Nature has evolved powerful metalloenzymes based on earth abundant base metals like iron that are capable of selectively cleaving and functionalizing C—H bonds. Cytochrome P450 enzymes contain an iron-heme center that reacts with oxygen and water to form high-valent iron-oxo intermediates. These species can directly and selectively convert C—H bonds into C—O bonds, even in complex molecule settings. However, the analogous transformation of C—H bonds to C—N and C—C bonds via metallonitrenes and metallocarbenes is not known in nature. The majority of synthetic, small molecule catalysts thus far developed for these C—H functionalization processes have been comprised of precious or noble metals like palladium, rhodium, ruthenium, and iridium. This work describes the discovery and development of two novel base metal catalysts for C—H amination and alkylation that proceed through high-valent metallonitrene and carbene intermediates. First, a C—H amination catalyst, manganese tert-butylphthalocyanine [Mn(tBuPc)], is described. This catalyst is an outlier to the reactivity-selectivity paradigm, i.e. is capable of oxidizing strong aliphatic C(sp3)—H bonds while displaying chemoselectivity (i.e. tolerance of more oxidizable functionality). It is unique in its capacity to functionalize all types of C(sp3)—H bonds intramolecularly, while displaying excellent chemoselectivity in the presence of π-functionality. Mechanistic studies indicate that [Mn(tBuPc)] transfers bound nitrenes to C(sp3)—H bonds via a pathway that lies between concerted C—H insertion, observed with reactive noble metals (e.g. rhodium), and stepwise radical C—H abstraction/rebound, observed with chemoselective base metals (e.g. iron). Rather than achieving a blending of effects, [Mn(tBuPc)] aminates even 1° aliphatic and propargylic C—H bonds, reactivity and selectivity unusual for previously known catalysts. Second, a C—H alkylation catalyst, iron phthalocyanine [FePc], is described that is capable of alkylating allylic, benzylic and ethereal C(sp3)—H bonds via a metallocarbene intermediate. The catalytic transformation of a C(sp3)—H bond to a C(sp3)—C bond via an iron carbene intermediate represents a… Advisors/Committee Members: White, Christina (advisor), White, Christina (Committee Chair), Denmark, Scott E (committee member), Hull, Kami (committee member), Katzenellenbogen, John (committee member).

▼ As one of the most commonly applied semiconductors, nanostructured silicon has received considerable attention over the past several decades due to its suitable band gap for light harvesting (1.2 eV for bulk crystal and up to 1.9 eV for nanocrystals), unique tunable photoluminescence (PL) and high biocompatibility and low toxicity. Significant effort has been made to fabricate and optimize silicon nanocrystal (SiNC) based devices. However, numerous important fundamental questions still remain. Therefore, this thesis mainly focuses on the elucidation of several fundamental research topics in the SiNC area, including nanocrystalline morphology control and evolution, surface functionalization and corresponding optical response of SiNCs, as well as the synthesis of particle/polymer hybrid materials. The thesis starts with an introduction about physical and chemical properties of SiNCs, general synthetic approaches, the present strategies of morphology control, as well as numerous surface modification approaches. Then details of a convenient method for preparing alkyl-functionalized silicon nanocubes are provided in Chapter Two with discussions about the mechanism of the particle size and shape control. Chapter Three focuses on the “one-pot” synthesis of homogenous SiNC/polystyrene hybrid materials. Also, three prototype micro/nano structures were fabricated for the demonstration of the utility of material hybrid characteristics such as bright photoluminescence (PL), high solvent processability and chemical stability. In Chapter Four, surface functionalization of SiNCs via thermally induced hydrosilylation is reexamined. The successful ligand functionalization processed at various temperatures under air atmosphere and the formation of ligand oligomers on SiNCs were noticed. These strongly suggest that an alternative mechanism exists to promote low temperature thermal hydrosilyaltion as well as ligand oligomerization on SiNCs. The potential influence of surface oxide species on SiNC optical properties is further described in Chapter Five. Based on a systematic study, it is clear that the surface defects or traps created by suboxides are strongly relevant to the non-phonon assisted nanosecond PL lifetime decay found from yellow/orange emitting ligand-functionalized SiNCs. Finally, Chapter Six presents the conclusions of each chapter and some recommended future work relative to SiNC science.

▼ Ultrashort laser pulses are used to impart huge peak intensities in short periods of time while producing very little thermal radiation that would affect surrounding material, allowing for features with higher aspect ratios than would be possible with longer pulse or continuous wave laser systems. This dissertation deals with femtosecond laser material interactions and the novel structures and functions that they can impart. Topics explored include laser systems, basic ultrafast laser ablation dynamics, laser structuring of metals, the ability of laser structures to add functionality to materials, and the translation of these functionalizing structures using scalable means. We begin our investigation of femtosecond laser-induced surface structures with a systematic study of laser ablation at varying incident angles, with particular focus given to the oft-neglected considerations of large incident angle dynamics. At such angles, much of the laser’s power is reflected, and the beam’s profile becomes highly elongated, resulting in novel laser-induced structural patterns and formation mechanisms. Questions addressed include: why certain structures form at these oblique incident angles, and how these structures’ patterns depend on angle, polarization, and pulse number. Structures created through femtosecond laser irradiation can also add functionality to materials. Functionalities discussed and studied include wetting properties such as hydrophobicity, optical properties such as color, and many others. Additionally, we address the ability to not only add functionality to materials through femtosecond laser irradiation, but to add mixed functionality (i.e. multiple properties imparted simultaneously). Functionalizing materials through laser ablation is a non-chemical means of adding such properties and is highly appealing to a number of industries and applications. To facilitate large scale commercial applications, nanoimprinting of femtosecond laserinduced structures through hot-embossing on commercially relevant plastics is studied and discussed.

▼ As a result of the increasing production of natural gas in the U.S., there is a demand to utilize its main component, methane, as a C1 source for value-added products, such as gasoline or diesel fuels. The industrial conversion of methane to liquid fuels uses multi-step processes with heterogeneous catalysts, which require high energy input and result in poor selectivity for the desired products. An attractive alternative to this method employs homogeneous catalysts to perform the oxidative coupling of methane. This approach could directly access higher alkanes at lower temperatures to achieve a more mild and selective process. Additionally, mechanistic insight gained from well-established solution-phase techniques could help improve the yield and selectivity in such homogeneous reactions. The proposed mechanism to form the initial product ethane from methane involves: (i) C‒H activation of methane to generate a M-CH3 intermediate, (ii) oxidatively-induced disproportionation between M‒CH3 intermediates to form a M‒(CH3)2 species, and (iii) reductive elimination from M‒(CH3)2 to liberate ethane. Chapter 2 describes the stoichiometric oxidation of homogeneous mono-methyl PdII complexes to selectively generate ethane. Experimental and computational studies support the formation of a dimethyl PdIV intermediate from methyl transfer. These studies demonstrate steps ii and iii of our proposed catalytic cycle. In Chapter 3, step i of the cycle, C‒H activation, is examined using a model system. PdII species and AgOPiv are employed in the C-H activation of pentafluorobenzene, through the formation of a Ag-C6F5 intermediate. Experimental evidence supports a Ag-mediated activation of pentafluorobenzene to form Ag-C6F5, followed by transmetalation to Pd, generating the PdII product. Chapter 4 explores the conversion of methane to ethane based on mechanistic information gained in the aforementioned stoichiometric studies of steps i, ii, and iii. High throughput experimentation demonstrates the formation of ethane from several reactions containing Pd or Pt catalysts, which are further pursued upon the development of a method to quantify the gaseous products. These studies reveal that a significant decomposition pathway to form ethane arises from ligand decomposition, and that ligand modification suppresses this side reaction. Further studies with these modifications are being pursued in order to achieve methane coupling.

▼ This thesis summarizes our efforts in the development of methodologies aimed at remote C(sp3)–H functionalization of aliphatic amines. Amines are an important functional group present in a variety of biologically relevant molecules; however, examples of remote C–H functionalization of unprotected amines remain scarce. Many of the challenges associated with the remote functionalization of amines are related to the susceptibility of C–H functionalization proximal to the nitrogen center. Chapter 1 provides a perspective and summary of the field and Chapters 2-5 cover strategies we have developed to perform selective, remote C(sp3)–H functionalization of aliphatic amines. We have employed protonation as a strategy in combination with platinum-catalysis to achieve terminal-selective functionalization of aliphatic amines (Chapter 2). This strategy is based on the in situ formation of an ammonium salt to deactivate the C–H bonds proximal to nitrogen. Similarly, Chapter 3 describes the remote oxidation of 2º and 3º C–H bonds of protonated aliphatic amines mediated by potassium persulfate. In contrast to Chapters 2 and 3, Chapters 4 and 5 describe our efforts on the palladium-catalyzed, directed method that takes advantage of the basic nitrogen atom to enable transannular C–H functionalization of biologically relevant cyclic amine scaffolds. In Chapter 4, we optimized conditions to accelerate functionalization and directing group removal steps to enable the rapid generation of fragments. Chapter 5 describes the ligand-effects that led to our second-generation conditions for transannular C‒H arylation that allowed for the functionalization of pharmaceutically relevant bicyclic amines. Mechanistic studies are presented along with preliminary studies on the incorporation of additional functional groups.

▼ Compared to conventional synthetic polymers, protein-based materials have unique advantages, such as useful mechanical properties, biocompatibility and biodegradability. Protein-based materials have the potential to be customized for a variety of applications, for example, biosensor, tissue engineering scaffolds and drug delivery vehicles. All these applications require optimizing the mechanical properties and adding functional proteins. Current methods to produce and functionalize protein-based materials are often performed in harsh conditions, which is harmful for the functional molecules. Our laboratory discovered a protein-based biomaterial made from the Drosophila protein, Ultrabithorax (Ubx). Ubx protein rapidly self-assembles into material in mild aqueous buffers. This work explores the possible applications of Ubx materials, by extending the capacity to engineer the mechanical and functional properties of these materials. Our first objective of this work was to investigate the structure and assembly of Ubx materials. We found the strength of Ubx materials is due to dityrosine bonds and located the amino acids that participate in these bonds. Tyrosine mutagenesis can decrease the strength of these materials, allowing the mechanical properties to be precisely tailored for a variety of applications. Our second objective was to study how the physicochemical properties of appended proteins impact the production of monomer and assembly of Ubx materials. By fusing proteins with a variety of physicochemical properties to Ubx. We demonstrated that the appended proteins dictate the solubility and purification yield of the corresponding protein fusions. Surprisingly, all protein fusions self-assemble equally well to produce materials with similar morphologies. We concluded that a far wider range of proteins can be successfully incorporated into elastomeric protein-based materials than originally anticipated. Finally, we used Ubx materials as tissue engineering scaffolds. We found VEGF-Ubx materials trigger corresponding signaling and stimulate migration and attachment of endothelial cells, proving that Ubx material can deliver appended functional molecules to attaching cells in vitro. In summary, this research explores a new way to control the mechanical properties of protein-based materials, reveals the great potential of Ubx materials as a system for functionalizing materials, and demonstrates the feasibility of using Ubx materials as bioactive tissue engineering scaffolds.
