光敏性树形聚合物的研究进展

Development of Photosensitive Polymer with Dendritic Structure

本文对光敏性树形聚合物的研究进展进行综述,介绍了光敏性树形聚合物的结构,其中重点介绍了树形聚合物进行光敏功能化的方法,分为外围光敏化、内核光敏化及内外双重光敏化三种方法。本文通过研究最为广泛的两类光敏性树形聚合物(分别含香豆素基团和螺吡喃基团),分析了聚合物树形结构对光敏基团性能的影响。

The research progresses on photosensitive dendritic polymer were reviewed. The structures of the dendritic polymers were introduced; the photosensitivity functionalization for the dendritic polymers was emphatically,including peripheral functionalization,core functionalization and internal/external double functionalization. Based on two kinds of photosensitive dendritic polymers（ containing coumarin group or spiropyran group,respectively） that studied most widely,the relationships between photosensitivity of the groups and structures of dendritic polymers were discussed.
