Abstract

PBDTBO, a conjugated polymer comprising benzo[1,2-b:4,5-b′]dithiophene (BDT) and 5,6-bis(octyloxy)benzo[c][1,2,5]oxadiazole (BO) units, exhibits a deep HOMO energy level of −5.27 eV and excellent solubility. A device incorporating PBDTBO and [6,6]-phenyl-C61-butyric acid methyl ester (1 : 1, w/w) exhibited a power conversion efficiency of 5.7%.
