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-T...
