article, dendronized polymers with rigid backbones were synthesized from enediyne‐containing Frechet‐type dendrimers. Two generations of dendrimers were conically incorporated with 3‐(2‐(2‐(trimethylsilyl)ethynyl)phenyl)prop‐2‐yn‐1‐ol. The trimethylsilyl protection groups of enediyne units were subsequently removed, and two types of brush polymers with rigid conjugated backbone were prepared through Bergman
在这篇文章中,具有刚性骨架的树枝状聚合物是由含烯二炔的Frechet型树枝状聚合物合成的。将两代树枝状聚合物与3-(2-(2-(3-(三甲基甲硅烷基)乙炔基)苯基)prop-2-yn-1-ol圆锥形结合。随后除去烯二炔单元的三甲基甲硅烷基保护基,并通过在真空下在升高的温度下通过Bergman环化聚合反应制备具有刚性共轭主链的两种类型的刷聚合物。用GPC,IR,UV-vis和NMR光谱对树枝状聚合物进行了表征。此外,通过原子力显微镜揭示了树枝状聚合物的形态。©2011 Wiley Periodicals,Inc. J Polym Sci A部分:Polym Chem,2011年
