relationship between the structures and light emission properties of five aryl-substituted pyrrole derivatives was studied during aggregation in THF−water mixtures. Only pentaphenylpyrrole clearly shows, however, an aggregation-induced emission enhancement (AIEE) phenomenon. On comparison of the optical properties and single-crystal structures of these pyrrole derivatives, it is suggested that the more twisted
研究了五种芳基取代的吡咯衍生物在四氢呋喃-水混合物中聚集期间的结构与发光性质之间的关系。但是,只有五苯基吡咯清楚地显示了聚集诱导的发射增强(AIEE)现象。通过比较这些吡咯衍生物的光学性质和单晶结构,可以看出,导致共轭生色团平行取向并受分子内旋转(RIR)效应限制的扭曲结构更多,是AIEE现象的主要原因。
