Synthesis,Properties,and Structures of Difluoromethylene-bridged Coplanar p-Terphenyl and Its Aryl-capped Derivatives for Electron-transporting Materials

摘要

A series of oligophenylene.derivatives consisting of 6,6,12,12-tetrafluoroindenofluorene moieties were synthesized.Photophysical properties and X-ray analyses clearly showed that these conjugated molecules have potentials for electron-transporting materials.
