Abstract
This thesis is divided into two parts, in the first part, β-diketone equipped with functional sites for Suzuki coupling polymerization has been synthesized via Claisen condensation. The designated functionalized diketone was chelated to iridium (III) center bearing with different cyclometalated ligands to form phosphorescence-emitting red-BTPBr, green-PPYBr, and sky blue-DFPBr complexes. These complexes were used as guest-monomer covalently attached to common fluorescent host-monomers to generate new light-emitting polymeric materials via Suzuki polymerization. These phosphorescent polymers exhibited improved efficiency in host-guest energy transfer, which could be potentially used to simplify device fabrication processes. The second part of this thesis deals with the synthesis, physical properties and characterizations of structural features of new thiophene-embedded chiral polymers. Thiophene fused to a carbocycle bearing with two chirality centers originated from natural L(+) and unnatural D(-) tartaric acids was synthesized to be the chiral monomers which was coupled with two conjugated monomers, respectively, via Suzuki coupling polymerization to give novel chiral polymers. Investigations on the photophysical and optical properties of these polymers in various solvent systems as well as solid thin films with different temperature variations were conducted to probe the intra- and inter-chain interactions. By comparison to those of their low molecular weight counterparts, helical structures formed within the polymeric chain were proposed. These oligomers and copolymers may be served as potential candidates to optoelectronic applications such as polarized light source or chiral dopant in liquid crystal displays.
