Photoconductivity of polystyrene with C60 in the side group

A series of polystyrene resin with C60 in the side group were prepared by chloromethylation, azidation and cycloaddition. In these C60-containing polystyrene resins, the C60 contents are about 2.9%, 6.7% and 11% (mass fraction), respectively. With the increase of C60 content in the C60-containing polystyrene resin, the photoconductivity increases obviously. α-NP as the charge transport material is better than DMMP, which proves that it is very important that charge transport material (CTM) match the charge generation material (CGM). If no charge transport layer in the photoreceptor exsist, the polystyrene resin with C60 in the side group could not show any photoconductivity at all.
