A small push-pull molecule involving a diphenylamine substituted by an oligo-oxyethylene chain is described. The compound exhibits aggregation-induced emission with solvent-dependent emission wavelength. Spin-cast deep-red amorphous films rapidly self-reorganize into colorless crystalline films which exhibit mechanofluorochromism and aggregation-induced second-harmonic generation.
本文描述了一种小分子推拉分子，其结构为二苯胺取代的寡氧乙烯链。该化合物具有聚集诱导发光性质，且发光波长随溶剂变化。旋涂的深红光非晶薄膜能够快速自组装成无色结晶薄膜，表现出力致变色和聚集诱导二次谐波产生性能。
