| 摘 要： | 通过对3种主链分别带有联吡啶、吡啶和苯的阴离子型水溶性聚对芳撑乙炔水溶液中加入不同价态的过渡金属离子,研究其紫外吸收和荧光发射谱图的变化,了解水溶性聚对芳撑乙炔产生荧光猝灭的机理.研究表明,过渡金属离子的价态会影响聚合物在水溶液的链积聚程度,并最终对共轭聚合物猝灭效应产生很大的影响.

| Abstract: | The fluorescence quenching of three anionic water-soluble conjugated polymers with Bipyridine, pyridine and benzene groups in the main chains by transition metal ions were investigated and compared with each other through UV-vis and fluorescence spectroscopy. It was found that the interchain aggregation and the fluorescence quenching were highly influenced by the valence of transition metals in aqueous solution. |
