Synthesis, self-assembly and photovoltaic applications of tribenzopentaphene derivatives

Abstract

Four tribenzopentaphene (TBP) derivatives containing different alkoxy side chains have been synthesized and shown to self-assemble into different microobjects such as microspheres, microfibers and microribbons. Photovoltaic cells of 1b blended with PDI or PC₆₁BM are fabricated and preliminary results show good efficiencies comparable to those of previously reported photovoltaic devices of hexabenzocoronenes.
