A series of novel oligomer-like molecules were synthesized. Cz(DPPCz)2 achieved the most satisfactory regulation with the band gap of 1.32 eV and the PCE was 6.12%, which is three times higher than the small molecule counterpart DPP(Cz)2.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
