摘　　要：聚集诱导的荧光增强(AIEE)现象是近几年备受关注的一个研究领域,文中纵观了该领域的进展,做了一个较为详尽的综述报道。具有该性质的体系主要包括多苯基取代的烯烃类、吡喃的衍生物以及二苯基二苯并环戊二烯类等。这种反常的聚集荧光增强现象多数是由于固态或聚集状态下分子内的自由旋转运动受到极大的抑制所引起的。对于具有AIEE性质化合物的结构-性质研究有利于寻找更有效的发光功能材料。Organic systems with aggregation induced enhanced emission （AIEE） have received increasing in terest in recent years. AIEE is an exceptional phenomenon for organic light-emitting materials, and the restricted intramolecular rotation is regarded as the main possible mechanism for its generation. This review summarizes the recent advances in this field,especially about the related organic or hybrid systems, which mainly include phenyl substituted olefins, diphenyl dibenzofulvenes, pyran derivatives and so on. It is thought that further investigation into the structure-property relationship of AIEE compounds will give us some useful information and even more new opportunities to develop more efficient organic light-emitting materials through this touch.
