Preparation and Characterization of Fullerene C_(60) and Phthalocyanine Co-grafted Poly(epoxy propyl carbazole)

The fullerene C-60 and phthatocyanine co-grafted poly (epoxy propyl carbazole) (C-60-CuPC-PEPC) was synthesized by Friedel-Crafts reaction. It was found that C-60-CuPc-PEPC had good UV-Vis absorption property, whose active spectral range was expanded from UV to visible spectrum region, and exhibited better photoconductivity than CuPc-PEPC and PEPC. These improvements could be attributed to the interaction between C-60, phthalocyanine and PEPC.

Optical Properties of Fullerenated Poly(epoxy propyl carbazole)

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