Stilbene derivatives have been widely used for the construction of molecular switches having stimulus-response properties. Unlike the well-known tetraphenyl ethylene derivatives that have aggregation-induced emission (AIE) properties, it is a challenge to develop a stilbene molecular switch with AIE function. In this paper, a new type of stilbene molecular switch with AIE function was constructed by the supramolecular interaction of pillar[5]arene. This type of molecular switch has excellent thermal stability, and quantitative ZE conversion can be achieved under acid catalysis. The light-driving reverse process achieved 87% of Z-configuration selectivity in the photostable state (PSS). The introduction of pillar[5]arene did not affect the switching performance of the parent compound. In a mixed solvent [tetrahydrofuran (THF)-H2O], a stable aggregate was formed due to the supramolecular self-assembly of pillar[5]arene, which showed the AIE performance that the parent stilbene derivative did not possess. This supramolecular strategy opens a new window for building AIE-type molecular switches.
