摘　　要：To achieve well defined amphiphilic C 60 containing macromolecules,C 60 conjugated polystyrene(C 60 PS)was first synthesized via tandem atom transfer radical polymerization(ATRP).With the help of tetrabutylammonium bromide(TBAB),taurine(2 aminoethanesulfonic acid) can be carried from water phase into the phenyl chloride phase and then react with C 60 PS.The final product——taurine modified C 60 conjugated polystyrene—is a novel type of highly asymmetric amphiphilic diblock copolymers,which can form spherical crew cut type micelles by adding water in small amounts into its tetrahydrofuran solution.UV vis spectroscopy and trasmission electronic microscopy have been employed to monitor the aggregating process of these spherical micelles and observe their final morphology respectively.To achieve well defined amphiphilic C 60 containing macromolecules,C 60 conjugated polystyrene(C 60 PS)was first synthesized via tandem atom transfer radical polymerization(ATRP).With the help of tetrabutylammonium bromide(TBAB),taurine(2 aminoethanesulfonic acid) can be carried from water phase into the phenyl chloride phase and then react with C 60 PS.The final product——taurine modified C 60 conjugated polystyrene—is a novel type of highly asymmetric amphiphilic diblock copolymers,which can form spherical crew cut type micelles by adding water in small amounts into its tetrahydrofuran solution.UV vis spectroscopy and trasmission electronic microscopy have been employed to monitor the aggregating process of these spherical micelles and observe their final morphology respectively.
