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
设计并合成了两个结构非常相似的四苯基
乙烯(TPE)功能化的螺
吡喃(
SP)分子。这两个分子具有聚集诱导发射(AIE)特性以及多刺激响应的变色特性,例如光致变色和酸致变色。对它们不同的光致变色和酸致变色特性以及异构化过程中的双响应荧光开关的研究表明,TPE和
SP之间的不同连接位置会显着影响扩展的π共轭体系,从而导致完全不同的光致变色和酸致变色特性。
