设计并合成了9，10-二（丁氧基苯乙烯基）蒽（DSA 4）的异构体，包括邻位和帕拉的正丁基、异丁基和叔丁基。它们都表现出聚集诱导发射现象。值得注意的是，它被发现，丁基端基的异构化提出了显着的影响，其压致荧光性能。因此，一种替代的方法来设计和获得压致荧光变色化合物在这里提出。
Isomers of 9,10-bis(butoxystyryl)anthracene (DSA4), including n-butyl, i-butyl and t-butyl at ortho or para positions, were designed and synthesized. All of them display an aggregation-induced emission phenomenon. Remarkably, it was found that isomerization of butyl endgroups presents significant influences on their piezofluorochromic properties. Thus, an alternative approach to design and obtain piezofluorochromic compounds is proposed here.
