| 제목 | Side Chain Effects on the Crystallinity and Solubility of Conjugated Polymers in Organic Photovoltaics |
| 초록 | In recent years, many types of side chains were introduced to conjugated polymer backbones for enhancing molecular weight, solubility and processability. Moreover, these enabled conjugated polymers and fullerene derivatives to mix properly, and controlled intermolecular interaction. Benzo[1,2-b:4,5-b`]dithiophene(BDT) is well known as a good electron donating unit, having a good carrier mobility and coplanar structure. Polythiophene showed a good hole mobility, but had low solubility in common organic solvents. In this study, BDT and bithiophene were polymerized by Stille coupling reaction. The synthesized polymers, PBDTBiTh(2EH) and PBDTBiTh(12C), had 2-ethylhexyl and n-dodecyl side chain on the 4,4` positions of bithiophene, respectively. The synthesized copolymers were characterized by 1H-NMR, GPC, UV-visible spectroscopy and cyclic voltammogram. |
