Solvent-vapor-annealed A–D–A-type semicrystalline conjugated small molecules for flexible ambipolar field-effect transistors

Abstract

This paper reports a series of acceptor–donor–acceptor-type small molecules based on an oligothiophene–phenylene core with three different electron-accepting terminal groups—dicyanovinyl, cyano-rhodanine, and cyano-indanone, respectively—for application to flexible ambipolar organic field-effect transistors.
