Abstract
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.
摘要
制备了一种前所未有的中修饰柱[5]芳烃衍生物EtP5A-DPE，其嵌入了一个四苯乙烯（TPE）单元，并对其进行了结构表征。在晶体中，客体1,4-二氰基丁烷分子在嵌入四苯乙烯的柱支架内的孵育诱导了分子构象的显著变化，关闭了该化合物的聚集诱导发光（AIE）发射。
