[Photoluminescence study of star-like C60(CH3)x(PAN)x copolymer]

Thin film of new synthesized C60(CH3)x(PAN)x copolymer was fabricated by physical jet deposition (PJD) technique. C60 molecule lies in the center of the star-like copolymers. PAN main chain is modified around the C60 molecules. Absorption and photoluminescence spectra show that there are strong interaction between C60 molecule and PAN, which depends on the length of PAN chain. Partly excitation transfer process between C60 molecule and PAN was observed, which leads to the fluorescence quenching of the PAN.
