摘　　要：聚集态诱导发光(AIE)现象自2001年被发现以来发展十分迅速,从早期的小分子体系逐渐发展到高分子聚合物体系。与传统的小分子相比,聚合物体系的AIE材料能够克服加工上的难题,为制备高效发光器件创造了良好条件。AIE机理随着体系的开发不断发展,其核心依然是分子聚集态变化导致的辐射跃迁渠道,每一种AIE现象的形成往往需要几个因素协同作用,机理的不断完善一方面很好地解释了现有的AIE现象,另一方面为开发出新的AIE体系奠定了理论基础。本文总结了几种在小分子基础上形成的聚合物AIE体系,并在现有的机理基础上介绍了几种较新的AIE机理。Phenomenon of aggregation-induced emission （ALE）, discovered in 2001, has been developed rapidly from early small molecules to polymer systems. Compared with traditional small molecules, polymer materials with AIE property can overcome the problems on processing and create favorable conditions for the preparation of highly efficient light-emitting devices. AIE mechanisms with the unchanged core of radiative transition channels caused by aggregation are developing with the discovery of AIE systems. The formation of each AIE phenomenon often requires the synergy of Several factors. Continuous improvement of the mechanism on one hand help to explain the AIE phenomenon, on the other hand lay the theoretical foundation for the development of a new AIE system. This paper summarizes several polymer AIE systems which are formed on the basis of small molecules and introduces some relatively new AIE mechanisms based on the existing ones.
