Tetraazabenzodifluoranthene Diimides: Building Blocks for Solution‐Processable n‐Type Organic Semiconductors

Abstract

11-Ring heterocyclic diimides were synthesized and found to be planar and to exhibit a slipped face-to-face π stacking. Variation of the substituents tunes the electronic structure and properties. In n-channel organic field-effect transistors, the new organic semiconductors have a high electron mobility. When they were used as acceptor material in polymer solar cells, a power conversion efficiency of 1.8 % was obtained.
