Preparation and Novel Optical Properties of Fullerene- based Polymer Materials

Synthesis of fullerene polymers has stimulated great interests of polymer scientists because suitably-designed fullerene polymers would be well processable and may also exhibit novel properties which are superior to those of the parent forms. Many different kinds of fullerene functionalized polymers have been prepared. In the letter, we prepared C 60 and phenylacetylene copolymers with C 60 content of 4.6 wt% and 9.6 wt% using organic metallic catalyst. Their structure were characterized using GPC, FTIR, NMR and UV spectrometer, respectively. The copolymers effectively limit strong 532-nm laser pulses. A new blue fluorescence with an emission peak wavelength at ca. 470 nm in the copolymers was found when the copolymers were excited at the wavelength of ca. 400 nm and its intensity increases with more C 60 in the copolymers.
