摘要

以对羟基苯甲酸和丙烯酰胺为配体,合成了铕-对羟基苯甲酸-丙烯酰胺三元稀土配合物,利用该三元稀土配合物中游离的羟基作为活性基团,以二丁基二月桂酸锡(T-12)为催化剂,与具有活性基团异氰酸根的甲苯-2,4-二异氰酸酯(TDI)反应制备新的键合型稀土高分子聚氨酯发光材料。通过红外、热分析和荧光光谱分析表征了发光材料的结构、热稳定性和发光性能,结果表明,TDI中异氰酸根的特征2270cm-1吸收峰消失,含羟基的铕配合物与异氰酸酯单体反应完全;在214nm波长激发下,配合物及发光材料在619nm和592nm处均能发出较强的特征荧光,预计在新型发光涂料方面有着广阔的应用前景。

Abstract

A ternary complex Eu(AM)2(HDBA)3·H2O was synthesized using the ligands p-hydroxybenzoic acid (HDBA) and acrylic amide (AM). The labile —OH functional group in the ternary complex was used to react with the —NCO functional group of toluene diisocyanate (TDI) in the presence of a dibutyltin dilaurate (T-12) catalyst. A novel photoluminescent material containing both rare-earth and polyurethane polymer was obtained and characterized by FT-IR, thermogravimetric analysis and fluorescence spectroscopy. The characteristic IR absorption band of isocyanate at 2270cm-1 was not present in the product showing that all the monomer had been consumed. Both the ternary complex and photoluminescent polymer material emitted characteristic fluorescence at 619?nm and 592?nm after excitation at a wavelength of 214nm, and have potential applications as new luminescent paint. 
