Synthesis, structure and optical properties of tetraphenylethene derivatives with through-space conjugation between benzene and various planar chromophores

Abstract

Through-space conjugation is conducive to efficient multidimensional exciton diffusion and charge transport in optoelectronic functional materials. Herein, a series of tetraphenylethene derivatives with through-space conjugation formed between benzene and various aromatic rings are synthesized and characterized. Their crystal structures, frontier orbital distributions and aggregation-enhanced emission properties are investigated.
