Novel C3-symmetric n-type tris(aroyleneimidazole) and its analogs: synthesis, physical properties and self-assembly

Abstract

Novel n-type C₃-symmetric materials are synthesized and shown to have desirable bandgap, broad absorption and high thermal stability, thus pose as viable candidates for organic photovoltaics. The strong intermolecular interactions among the extended π-surfaces beget the self-assembly of nanofibers.
