The optical properties of the fullerenated poly(epoxy propyl carbazole) (PEPC) havebeen investigated. Compared with pure PEPC, fullerenated PEPC has the same structure inthe UV region of the absorption spectrum, and extends the active range to a longerwavelength. The apparent quenching of PEPC fluorescence was observed in thefullerenated polymer and it can be attributed to intramolecular excited state energytransfer.
