摘要：
A newly designed 2-arylbenzimidazole derivative which plays a role of co-acceptor unit has been prepared for the synthesis of conjugated polymer. 2-arylbenzimidazole derivative has been incorporated into 4,7-dithiophen-2-yl-benzo(2,1,3)thiadiazole (TBT) and fluorene based alternating copolymers with different ratios of 5mol.% and 10mol.% named POFTBT-IMD5, POFTBT-IMD10, respectively. We also synthesized alternating copolymer of 9,9-dioctylfluorene and TBT (POFTBT) to compare physical properties. POFTBT-IMD5, POFTBT-IMD10 films showed absorption peaks at 559 and 555nm, respectively. The HOMO and LUMO energy levels of POFTBT-IMD5, POFTBT-IMD10 were -5.4/-3.84eV and -5.4/-3.81eV, respectively, which were similar to those of POFTBT (-5.3/-3.7eV).
