富勒烯高分子聚合物的制备及发光性能
Preparation and Photoluminescence Properties of Fulllerene (C 60 ) Polymer
【摘要】 采用金属钨催化剂和溶液聚合法 ,在室温下合成了C6 0 和 1 -苯基 - 1 -丙炔共聚物 ,对该共聚物的结构进行了表征 ,发现在聚合反应中C6 0 既作为共聚单体分子又呈现出催化剂的作用。详细地测试了聚合物的荧光性能 ,结果表明共聚物荧光发光光谱峰位置与激发光波长无关。对聚合物不同浓度溶液的测试和对聚合物发光机制的分析表明 :在聚合物链中含有不同发光结构点 ,共聚物呈现结构不均匀性
【Abstract】 In the paper, the copolymers of C 60 and 1-phenyl-1-propne with C 60 of 1.5 wt % was synthesized by WCl 6/Ph 4Sn catalyst systems at room temperature. High yield and high molecular weight polymer in polymerization reaction were obtained. The structure of the copolymer was characterized. The fluorescence emission properties of copolymer solutions with different concentration were investigated using variable excitation wavelength. The biggest fluorescence yield in the copolymer was showed at an excitation wavelength of 315 nm. The relation between fluorescence of polymer and their structure was studied. The results exhibited inhomogeneous distribution of emitting sites in the copolymers.
