Low band-gap donor–acceptor copolymers based on dioxocyclopenta[c]thiophene derivatives as acceptor units: synthesis, properties, and photovoltaic performances

New donor-acceptor type copolymers containing dihexyldioxocyclopenta[c]thiophene or (dihexylmethylidene)dioxocyclopenta[c]thiophene as acceptor units have been designed and synthesized for the application as hole-transporting (p-type) organic semiconducting materials in organic photovoltaics (OPVs)....
