Relationships among the Structures and Properties of the Pyrrole-fused Azacoronenes

Abstract

Large pi-systems as represented by hexabenzocoronenes (HBCs) have been attracted a great deal of attention from materials science partly due to their strong intermolecular interactions and their high charge carrier mobilities. Among them, nitrogen-incorporated pi-systems have potential advantages since such heteroatoms can tune the electronic nature without modifying the structure. In order to investigate the effect of the incorporated nitrogen atoms, we have newly designed and synthesized a series of nitrogen-incorporated large pi-systems.
