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 I have been employed to monitor the aggregating process of these spherical micelles and observe their final morphology respectively.
