strategy for the poly(benzyl ether) dendrimers having the tetraethyleneoxide at core via the copper-catalyzed 1,3-dipolar cycloaddition reaction between alkyne and azide was described. Tetraethyleneglycol diazide, designed to serve as the core in dendrimer, was stitched with the alkyne-functionalized poly(benzyl ether) dendrons by the click chemistry leading to the formation of triblock dendritic polymers
描述了通过铜催化的炔烃和叠氮化物之间的 1,3-偶极环加成反应,以四亚乙基氧为核心的聚(苄基醚)树枝状聚合物的收敛合成策略。设计用作树枝状聚合物核心的四乙二醇二叠氮化物通过点击化学与炔烃官能化的聚(苄基醚)树枝状化合物缝合,从而以高产率形成三嵌段树枝状聚合物。研究了树枝状聚合物的吸收和发射。树枝状聚合物的结构用 1H NMR、13C NMR、IR 光谱、质谱和凝胶渗透色谱表征。
