▼ A liquid crystal (LC) at its boundary surface adopts a preferential alignment, which is referred to as anchoring. The direction of this alignment (i.e., anchoring direction) may be perpendicular, parallel or tilted with respect to the surface. Transitions from one anchoring condition to another may occur when the parameters (e.g., temperature) charactering the surface change, as referred to as anchoring transitions. In the LC-polymer composite systems under our study, the anchoring and temperature- driven anchoring transitions of nematic fluids is very sensitive to the structure of the side chain of poly (alkyl acrylate) matrixes that encapsulate the LC. We have shown that the anchoring transition temperature of these systems can be tuned far below the nematic-to-isotropic transition temperature, by varying either the length, branching structure of the side chains of homopolymers, or the composition of copolymer of two dissimilar monomers. Both sharp and broad anchoring transitions with respect to the temperature range over which a transition occurs were observed. It is postulated that microscopic interactions between the polymer side chains and LC molecules play an important role in determining the anchoring. In particular, the conformation of the polymer side chain is proposed to have important control over the anchoring. Anchoring strength and tilt angle as a function of temperature during the anchoring transitions were also experimentally investigated, which contribute to understanding of the microscopic mechanism for such transitions. Based on the LC-polymer composites with controlled anchoring, a LC display with reverse switching mode and a novel electrically switchable diffraction grating have been demonstrated. The advantages of these devices are ease of manufacturing, low operation voltage, and mechanical stability offered by polymer matrix. Moreover, a detailed study of the director configuration of wall defects found in these composite films was carried out using fluorescence confocal polarized microscopy.

▼ Long-distance radical cation transport was studied in DNA condensates where linearized pUC19 plasmid was ligated to an oligomer and transformed into DNA condensates with spermidine. DNA condensates were detected by Dynamic Light Scattering and observed by Transmission Electron Microscopy. Introduction of charge into the condensates causes long-distance charge migration, which is detected by reaction at the remote guanines. The efficiency of charge migration in the condensate is significantly less than it is for the corresponding oligomer in solution. This result is attributed to a lower mobility for the migrating radical cation in the condensate, caused by inhibited formation of charge-transfer-effective states. Radical cation transport was also studied in DNA condensates made from an oligomer sandwiched between two linearized plasmids by double ligation. Unlike the single ligated plasmid condensates, the efficiency of charge migration in the double ligated plasmid-condensates is high, indicative of local structural and conformational transformation of the DNA duplexes. Organic monomer units having extended ð-conjugation as part of a long conducting polymer was synthesized and characterized. The monomer units were covalently attached to particular positions in DNA oligonucleotides by either the convertible nucleotide approach or by phosphoramidite chemistry. Successful attachment of the monomer units to DNA were confirmed by mass spectral analysis. The DNA-conjoined monomer units can self assemble in the presence of complementary sequences which act as templates that can control polymer formation and structure. By this method the para-direction of the polymer formation can be enforced and may be used to generate materials having nonrecurring, irregular structures. Advisors/Committee Members: Dr. Gary B. Schuster (Committee Chair), Dr. David M. Collard (Committee Member), Dr. Donald Doyle (Committee Member), Dr. Marcus Weck (Committee Member), Dr. Uzi Landman (Committee Member).

▼ Soft materials have attracted much scientific and technical interest in recent years. In this thesis, attention has been placed on the underpinning relations between molecular structure and properties of one type of soft matter - main chain liquid crystalline elastomers (MCLCEs), which may have application as shape memory or as auxetic materials. In this work, a number of siloxane-based MCLCEs and their linear polymer analogues (MCLCPs) with chemical variations were synthesized and examined. Among these chemical variations, rigid p-phenylene transverse rod and flat-shaped anthraquinone (AQ) mesogenic monomers were specifically incorporated. Thermal and X-ray analysis found a smectic C phase in most of our MCLCEs, which was induced by the strong self-segregation of siloxane spacers, hydrocarbon spacers and mesogenic rods. The smectic C mesophase of the parent LCE was not grossly affected by terphenyl transverse rods. Mechanical studies of MCLCEs indicated the typical three-region stress-strain curve and a polydomain-to-monodomain transition. Strain recovery experiments of MCLCEs showed a significant dependence of strain retentions on the initial strains but not on the chemical variations, such as the crosslinker content and the lateral substituents on mesogenic rods. The MCLCE with p-phenylene transverse rod showed a highly ordered smectic A mesophase at room temperature with high stiffness. Mechanical properties of MCLCEs with AQ monomers exhibit a strong dependence on the specific combination of hydrocarbon spacer and siloxane spacer, which also strongly affect the formation of ð-ð stacking between AQ units. Poisson s ratio measurement over a wide strain range found distinct trends of Poisson s ratio as a function of the crosslinker content as well as terphenyl transverse rod loadings in its parent MCLCEs.

Muzzy (Committee Member), Mohan Srinivasarao (Committee Member), Satish Kumar (Committee Member).

▼ Polythiophenes have great potential as semiconductors for use in organic field effect transistors and light emitting diodes. Recent research has been focused on the design, synthesis and characterization of fluorinated polythiophenes and oligothiophenes. Various fluoroalkyl side chains have been introduced to induce polymer self-assembly, to control the electronic properties of the conjugated backbone, and to modify the solubility of the polymer in supercritical CO2. This work led to the preparation of poly(3-(perfluorooctyl)thiophene), which is one of only a few examples of n-dopable polythiophenes, and is the first supercritical CO2-soluble conducting polymer. An alternating copolymer consisting of 3-perfluoroakyl and 3-alkylthiophene units has been synthesized. This polymer, with alternating electron-donating and withdrawing substituents, has a high quantum yield for fluorescence in solution relative to the two homopolymers, and strong fluorescence in solid state. Based on the study on its nanocrystals, the unusual photophyiscs may be due to the formation of the supramolecular structure with hexagonal packing. A novel thiophene monomer, 3-(1,1-difluorooctyl)thiophene, was prepared to further tune the electronic structure of polythiophenes by changing the fluorination pattern of side chains, while retaining solubility in organic solvents by virtue of the hydrocarbon side chain. a-Hexyl-w-perfluorohexylsexithiophene was synthesized to make a novel amphiphilic material for use in TFTs. Models for interchain charge transfer in doped conducting polymers were also developed. Stacked and unstacked conjugated oligomers have been synthesized as models for conducting polymers. The bis(radical cation) form and the dication-neutral form of compounds in which conjugated oligomers are held in a stacked arrangement are shown to coexist and in equilibrium with each other. The coexistence of these two forms further suggests that both may serve as charge carriers. Interconversion between these forms by disproportionation mimics a possible mechanism for charge migration in doped conjugated polymers. Advisors/Committee Members: David M. Collard (Committee Chair), CP Wong (Committee Member), Laren Tolbert (Committee Member), Marcus Weck (Committee Member), Morhan Srinivasarao (Committee Member).
