摘要
以聚醋酸乙烯酯 (PVAc)为配体 ,分别与SmCl3,NdCl3在乙醇中进行反应 ,生成PVAc Sm(Ⅲ ) ,PVAc Nd(Ⅲ )的配合物。用电导率法确定PVAc Sm(Ⅲ ) ,PVAc Nd(Ⅲ )配合物中Sm3+ ,Nd3+ 与PVAc链节单元 [-CH2 -CH (OCOCH3) -]的配比为 1∶6。IR和XPS测试表明 :PVAc的CH3COO中酯基氧共同提供电子与Sm3+ ,Nd3+ 形成配位键 ,溶剂分子C2 H5OH参与配位 ;TG DTA分析表明 :配合物的热分解温度比PVAc的低 ;荧光光谱显示 :PVAc Sm(Ⅲ ) ,PVAc Nd(Ⅲ )配合物具有荧光特性 ,分别在 42 7,418nm产生荧光。
The complexes of PVAc-Sm(Ⅲ), PVAc-Nd(Ⅲ) were synthesized by the reaction of SmCl 3, NdCl 3 with polyvinyl acetate in absolute alcohol. By the conductance ratio method, the mole ratio of metal ion to [-CH 2-CH(OCOCH 3)-] was 1∶6 in complexes. The complexes were charactrized by IR, XPS, TG, DTA and fluorescence spectra. All results show: the both oxygen in each [-CH 2-CH(OCOCH 3)-] coordinate with samsrium and neodymium ion, and solvent alcohol also coordinate with them. The strong fluorescence is found in their fluorescence spectrum.
