Abstract

A pro-aromatic bisphenaleno-thieno[3,2-b]thiophene (BPT-TIPS) was synthesized and compared with an anti-aromatic bisindeno-thieno[3,2-b]thiophene (S2-TIPS). BPT-TIPS showed larger diradical character, stronger absorption, longer excited state lifetime and better redox amphotericity than S2-TIPS. X-ray crystallographic analysis of BPT-TIPS disclosed an ordered 3D packing via close π-π interactions and field-effect hole mobility of 0.26 cm2V-1s-1 was obtained.
