An efficient convergent route to the main chain type of organometallic dendrimers, in which platinum moieties are linked by 1,3,5-triethynylbenzene, has been developed. The synthesis of platinum-acetylide dendrons involved the use of two types of trialkylsilyl groups for protection of the terminal acetylene. The platinum-acetylide dendrimers were prepared up to the third generation by reacting dendrons
已经开发出一种有效的收敛途径,该途径是有机金属树枝状聚合物的主链类型,其中铂部分通过1,3,5-三乙炔基苯连接。铂-乙炔树突的合成涉及使用两种类型的三烷基甲硅烷基基团来保护末端乙炔。通过使树枝状分子与三lat核和四铂核反应,制备至第三代的铂-乙炔树状大分子。凝胶渗透色谱的光谱表征和痕量实验表明,树状聚合物分子没有结构缺陷。尽管使用π-共轭体系作为桥联配体,但电子和荧光光谱表明,树枝状聚合物中的铂-乙炔基部分之间的相互作用很小。
