通过Frechet型树枝状二溴大分子单体和卟啉二硼酸频哪醇酯的Suzuki缩聚反应，合成了卟啉嵌入的高分子量树枝状聚合物（第四代）。高代侧向树枝状楔形不仅赋予树枝状聚合物在常用有机溶剂中良好的溶解性，而且通过其“位点隔离”效应阻止平面卟啉和共轭聚合物骨架聚集。这类卟啉嵌入的树枝状聚合物可以用作饱和红光发光材料。随着横向树枝化生成的增加，树枝化聚合物的量子产率也逐渐增加。© 2008 Wiley Periodicals，Inc.聚合物科学杂志A部分：聚合物化学46：4030-4037，2008
Porphyrin-embedded high molecular weight dendronized polymers up to fourth generation have been synthesized by Suzuki polycondensation of Frechet-type dendritic dibromo macromonomers and porphyrin diboronic pinacol ester. Higher generation lateral dendritic wedges not only endow the dendronized polymers with good solubility in commonly used organic solvents, but also prevent planar porphyrins and conjugated polymer backbones from aggregating by their “site isolation” effect. This type of porphyrin-embedded dendronized polymers can be used as saturated red light-emitting materials. With the increase of the generation of the lateral dendrons, the quantum yields of the dendronized polymers also gradually increased. © 2008 Wiley Periodicals, Inc.
