中文摘要:
tetraphenylethene (TPE ) 的二衍生物通过联合反应的一步十字 McMurry 被综合。两 luminogens 展览导致聚集的排放(AIE ) 和结晶化导致了排放改进(CIEE ) 。两 luminogens 的排出物能与热、器官的溶剂 fuming 和机械刺激通过形态学的可逆调整在蓝色和绿色之间被交换。因此,我们为交换材料的排放提供可能的设计策略。
英文摘要:
Two derivatives of tetraphenylethene (TPE) were synthesized through one step cross McMurry coupling reaction. Both lumino- gens exhibit aggregation-induced emission (ALE) and crystallization induced emission enhancement (CIEE). The emissions of both luminogens could be switched between blue and green through reversible modulation of morphology with thermal, organic solvent fuming and mechanical stimuli. Thus we provide a possible design strategy for emission switching materials.
