The goal of this research is to study the synthesis and application of new poly(3-hexylthiophene) derivatives. The first part of this study is to incorporate poly(3-hexylthiophene) (P3HT) into copolymer structure with poly(l-lactide) (PLLA) blocks via a feasible Grignard metathesis method to control the end-capping group, and ring-opening polymerization method to combine the l-lactide monomer. Different volume fractions of P3HT-PLLA were prepared with different molecular weight of PLLA. The chemical structure of the copolymers were investigated by 1HNMR and MALDI-TOF MS. Well-defined and phase-separated microdomains of P3HT-PLLA thin film can be observed by appropriate solvents and post-thermal treatment. The block copolymer films reveal pit-like surface morphology. After degradation of PLLA block, the films with large amounts of porous texture were formed and used as templates for the fabrication of organic solar cells. The OPV devices with P3HT nanoporous film show higher power conversion efficiency than that with pristine P3HT thin film. The second part of this study, we combined vinyl terminated poly(3-hexylthiophene) with 1,3,5,7,9,11,13,15-Octakis(dimethylsilyloxy)- pentacyclo[9.5.1.13,9.15,15.17,13]octasiloxane to synthesized new star-like P3HT polymer. This star-like polymer shows better film forming property and better device stability than the original vinyl-terminated P3HT. Chain-Shu Hsu 許千樹 2008 學位論文 ; thesis 97 zh-TW
