Abstract

N,N′-Substituted quinacridones are a novel class of commercially available quinacridones for organic electronics which are reported here. In this study, we performed in-depth investigations of the material properties of these molecules i.e. their optical and charge transport properties, infrared-active vibrations (FTIR), electrochemical reduction and oxidation properties, thin film forming and processability, and finally performance in organic field effect transistor devices. We show that substitution plays a critical role in the charge transport properties, with methyl substituted amine being the most favorable, followed by di-phenyl and finally di-butyl.
