A novel acceptor–donor–acceptor chromophore IDTT-HC2P with an indacenodithienothiophene core linked with two hydrazinylidenecyclopentadiene terminal acceptor groups was designed and synthesized via the reaction of dilithiated indacenodithienothiophene with the corresponding diazo compound. The frontier orbital energy levels as well as the bandgap which were estimated from both optical and electrochemical properties are very closely related to those of ITIC which in turn is associated with high power conversion efficiencies.
