摘要
合成表征了C60和苯乙炔共聚物。详细地测试了聚合物溶液的荧光性能。研究结果表明溶液浓度为0.5g/L时,聚合物呈现出了荧光浓度自猝灭效应。对于C60含量为5%的聚合物在350nm被激发时,荧光光谱除在440nm有一个聚苯乙炔的荧光发射峰之外,在404nm呈现出了一个新的弱荧光峰,聚合物中C60对这个荧光具有猝灭效应,聚合物发光机制被分析。
In the paper, the copolymers of C60 a nd phenylacetylene with C60 of 4.6wt% and 9.6wt% were synthesized and its structures were characterized. The fluorescence properties fro m the polymers in solution were studied. Typically concentration self- quenching effect of polymer in THF solution were found when the polym er concentration reaches 0.5mg/mL. The polymers excited at 350nm showed a new weak emission band at 404nm besides emission peak at 440nm o f polyphenylacetylene and further investigations indicated that fluoresce nce of polyphenylacetylene is quenched by the C60 site in the p olymer structure.
