Packing Structural Control of Fused Acene Compounds by Aggressive Intermolecular Interactions and Their Charge Transport Properties

Abstract

We have introduced aryl and perfluoroaryl groups as substituents into a series of fused acene core at several central positions. From the single crystal analysis, it is found that the aryl-perfluoroaryl interactions have successfully played important role in the induction of pi-pi interaction among acene core. The OTFT measurement reveals that FPPAs exhibited much higher hole mobilities than PPAs which do not have any aggressive interaction. This result strongly demonstrates that aryl and perfluoroaryl system could open up general and versatile strategy to control the molecular ordering, resulting in the creation of new semiconducting materials with high charge mobilities.
