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.
