Paper Abstract

We have fabricated thin film of the star-like C60(CH3)x(PAN)x copolymer. Optical property and ultrafast nonlinear optical response of the copolymer films were measured. The absorption and photoluminescence spectra showed the intramolecular excitation transfer process existed in the copolymer. From the femtosecond optical Kerr effect measurement, third-order nonlinear optical susceptibility of the copolymer film was found bigger than that of pure PAN and fullerene molecule which result from a new lower excited state and the redistribution of the electron cloud in the copolymer.
