Abstract

In this work two novel copolymers of Boron dipyrromethane (BODIPY) and Fluorene are designed, synthesized and their optoelectronics properties is reported. The polymers were designed to study the effect of the substituent at the meso position of BODIPY on the optoelectronic properties of the polymer. Changing the methyl group on the phenyl group at the meso position in the BODIPY subunit to trifluoromethyl group not only lowers the LUMO energy value but also improves the electron transport in the polymer. The polymers have also been used as electron transport material to fabricate all polymer solar cell and polymer photodetectors.
