Two tetraphenylethene-based tetracationic dicyclophanes 1 and 2 were synthesized via a one-step SN2 reaction. Based on the central TPE unit and the slight difference of the outer linkers, 1 and 2 exhibited a classic aggregation-induced emission but contrasting mechanochromic luminescence under grinding, vaporing, or hydrostatic pressure in the solid state, and photochemical reactions with various emitting colours induced by photoirradiation in the solution state.
通过一步SN2反应合成了两种基于四苯乙烯的四价阳离子双环笼状化合物1和2。基于中心TPE单元以及外部连接基团的微小差异，1和2在固态下研磨、蒸发或静水压力作用下呈现出典型的聚集诱导发光，但机械变色发光情况相反，并且在溶液状态下经光照射会引发具有各种发射颜色的光化学反应。
