초록

Novel push-pull organic semiconductors, bisDMFA-InTTh-MMN (1) and bisDMFA-InTTTh-MMN (2) containing planar and rigid indenothiophene or indenothienothiophene functionalities incorporated into a pi-conjugated thiophene bridge were synthesized and the photovoltaic performances in solution-processed small molecule organic solar cells (SMOSCs) were investigated. The planar indenothiophene skeleton induced the effective inter- and intramolecular charge transfers of these materials. The most efficient SMOSCs based on this novel indenothiophene exhibited a moderate PCE of 3.21% from a skeleton comprised of a bisDMFA donor, MMN acceptor, and InTTTh pi-linker.
