Preparation and Novel Optical Properties of Fullerene-based Polymer Mat

Synthesis of fullerene polymers has stimulated great interests of polymer scientists suitably-designed fullerene polymers would be well processable and may also exhibit novel propertie are superior to those of the parent forms. Many different kinds of fullerene functionalized polymers ha prepared. In the letter, we prepared C 60 and phenylacetylene copolymers with C 60 content of 4.6 w 9.6 wt% using organic metallic catalyst. Their structure were characterized using GPC, FTIR, NMR spectrometer, respectively. The copolymers effectively limit strong 532-nm laser pulses. A ne fluorescence with an emission peak wavelength at ca. 470 nm in the copolymers was found w copolymers were excited at the wavelength of ca. 400 nm and its intensity increases with more C 6 copolymers. 合適分子設計的C60 聚合物 ,具有優越于C60 本身的加工性能和新穎的光學性能 ,引起了人們的很大興趣 ,很多C60 功能高分子已被合成出來。在這篇論文中 ,我們使用有機金屬催化劑制備了C60含量分別為 4.6wt%和 9.5wt%的高分子共聚物。使用傅立葉紅外光譜、核磁共振光譜、凝膠滲透色譜和電子吸收光譜分別表征了聚合物的分子結構。共聚物對 532nm波長激光呈現出較好的光限幅性能 ,這種C60 聚合物具有新穎的藍光發光效應 ,發光效率隨聚合物中C60 含量的增加而增強 ,分析了聚合物的發光機制。
