High charge carrier mobility and efficient charge separation in highly soluble perylenetetracarboxyl-diimides

Abstract

In this communication we report on the synthesis and charge mobility of highly soluble perylenebisimid derivatives. We show that introduction of alkylester side chains results in compounds combining a high solubility with charge mobilities up to 0.22 cm² V⁻¹ s⁻¹. These materials are therefore interesting as an electron acceptor for solution-processed organic photovoltaics.
