| Abstract: | The fullerene reacts with free radicals produced by reaction of 3-chloromethyl-methixy benzene and CuBr to form multisubstituted fullerene derivant. The synthesis of multibranched fullerene polymer was achieved by condensation between 2,2-bis(hydroxymethyl)propionic acid and the fullerene derivant. They were characterized by FTIR, MULDI-TOF MS, TEMand GPC. The thin film was prepared by LBtechnique, and the film morphology was early investigated by AFM. |
