| 摘 要： | Ｃ６０是碳笼烯一族的代表，其独特的球笼形空间结构和电子结构决定了其有许多奇异的性质［１］．关于Ｃ６０的化学反应性的研究方兴未艾［２］，其中Ｃ６０的高分子衍生物的合成也是关注所在．迄今关于含Ｃ６０的高聚物的合成已有许多报道［３，４］，而关于窄分布的含Ｃ６０高聚物的合成的研究尚少．Ｆｒｅｙ等［５］将阴离子聚合所得的聚苯乙烯链的末端转变为氨基，再与过量的Ｃ６０发生单电子转移加成反应制得窄分布的以Ｃ６０封端的聚苯乙烯．Ａｓｔｒｕｓ等［６］将活性阳离子聚合所得的六臂星形聚苯乙烯的末端转化为氨基，得到Ｃ６０…

| Abstract: | C\-\{60\}\|end\|bonded polystryrenes(PS\|C\-\{60\}\|Br) with narrow molecular weight polydispersity were prepared by atom transfer radical polymerization (ATRP) in good yield.GPC results show that the polydispersities of these fullerene polymeric derivatives were between 1.1 and 1.3.The brown color of the solution indicates that C\-\{60\} has been bonded into the polymer,which was confirm by UV\|vis.Furthermore,2\|amino\|acetonictrile was used as an IR label to react with PS\|C\-\{60\}\|Br,and the product show the characteristic absorption of CN group at 2369cm\+\{-1\}.These results reinforce the conclusion that C\-\{60\} has been covalently bonded into the polymer.A possible mechanism of the formation of C\-\{60\}\|end\|bonded PSt was deduced tentatively. |
