Abstract

A new series of dithieno[3,2-b:2′,3′-d]pyrrole-incorporated oligomers was synthesized and characterized. The crystal structure, crystal packing, optical properties, electrochemical properties, and time-of-flight mobilities were investigated in detail. The oligomers are highly fluorescent in both solution and the solid state. The solution-state quantum yield of these new compounds ranged from 52 to 75%. Band gaps of these oligomers were found to be in the range of 2.5-2.8 eV. The surface morphology of the film was also characterized by atomic force microscopy. The material was found to be hole-transporting with a mobility on the order of 10-6 cm 2/(V s).
