Abstract
Perylene bisimide derivatives substituted with one and two tetraphenylethene moieties at 1 and 1,7-postions show distinct optical properties. The former displays characteristic emission features of perylene bisimides in solution and red emission in the aggregate state, while the latter is nonemissive in solution but highly red-emissive in the aggregate state.
摘要
取代 1 位和 1,7 位的苝二酰亚胺衍生物各有一个和两个四苯乙烯单元，表现出明显不同的光学性质。前者在溶液中显示出苝二酰亚胺的特征发射特性和聚集态下的红色发射，而后者在溶液中不发光，但在聚集态下具有很强的红色发光。
