An unprecedented meso-decorated pillar[5]arene derivative, EtP5A-DPE, embedded with a TPE unit was prepared and structurally characterized. In the crystal, the incubation of the guest 1,4-dicyanobutane molecule inside the tetraphenylethene-embedded pillar scaffold induces a significant change in the molecular conformation, shutting down the AIE emission of this compound.

构象受控的AIE发光剂的发射：四苯基乙烯嵌入的柱[5]芳烃骨架

制备了一种内嵌有TPE单元的前所未有的介孔装饰性柱[5]芳烃衍生物EtP5A-DPE，并对其结构进行了表征。在晶体中，四苯基乙烯嵌入的支柱支架内部的客体1,4-二氰基丁烷分子的孵育诱导了分子构象的显着变化，从而关闭了该化合物的AIE发射。
