BTP-4F-12

Description

BTP-4F-12 is an analog to Y6 with longer alkyl chains on its pyrrole rings. This imparts improved solubility to BTP-4F-12, meaning it can be solubilized in non-halogenated solvents such as o-xylene, TMB and THF. Its performance in organic solar cells remain among the best, reaching high PCEs up to 16.4% when used with the donor polymer T1 (Analog properties to PBDB-T-2F ).
