The fullerenated PEPC[Poly(epoxy propyl carbazole)] was synthesized by Friedel-Crafts type reactions. Molecular weights of the polymers were determined by gel permeation chromatography. Structures of the polymers were analyzed and characterized by use of proton and 13 C-NMR, IR, thermal analysis and optical spectroscopic methods. The 13 C-NMR spectrum of the fullerenated PEPC exhibits signal in the fullerene region. Compared with pure PEPC, the fullerenated PEPC has the same structure in UV region of the absorption spectrum and extends the active range to longer wavelength. The quenching of PEPC fluorescence was observed in the fullerenated polymer and it can be attributed to intramolecular excited state energy transfer. The fullerenated PEPC is soluble in common organic solvents such as THF and chloroform. The process can be generalized to other polymers having phenyl groups to produce a series of fullerenated polymers.
