BTP-4F-12 is also known as Y6-BO, BTP-4F-12. The Y6(BTP4F-8) alkyl side chain was modified to synthesize BTP-4F-12[1]. They have similar optical bandgap and different absorption coefficients. The UV absorption peak of BTP-4F-12 is approximately 820 nm[2]. As an optical bandgap non-fullerene acceptor materials, BTP-4F-12 can be used to prepare efficient binary small molecule organic photovoltaics and ternary organic photovoltaics.
