| Abstract: | Two tetraphenylethene (TPE)‐functionalized spiropyran (SP) molecules with very similar structure were designed and synthesized. The two molecules exhibit aggregation‐induced emission (AIE) properties, as well as multistimuli‐responsive color‐changing properties, such as photochromism and acidchromism. The investigation of their different photochromic and acidchromic characteristics and dual‐response fluorescent switch during isomerization indicated that the different link position between TPE and SP will significantly affect the extended π‐conjugated system, resulting in completely different photochromic and acidchromic properties. |
