以1,10-邻菲啰啉和2,7-二羟基萘-3,6-二磺酸钠为配体,合成了铕-2,7-二羟基萘-3,6-二磺酸-邻菲啰啉三元配合物{[Eu(HL)(phen)(H2O)](H2O)3}∞;利用配合物中未参与配位的-OH作为活性基团,以二月桂酸二丁基锡为催化剂,与具有活性基团-NCO的异佛尔酮-二异氰酸酯反应制备铕三元配合物-聚氨酯丙烯酸酯发光材料。通过X射线单晶衍射、红外、热分析和荧光光谱分析,测定了配合物及发光材料的组成、结构、热稳定性和发光性能。结果表明,在496 nm波长激发下,配合物及发光材料在610 nm处能发出较强的特征荧光,且随着配合物含量的增加,荧光性能增强,同时在测试范围内没有发生荧光淬灭现象,是一种极具潜在应用的新型发光材料。
Using 1,10-phenanthroline and 2,7-dihydroxynaphthalene-3,6-disulfonate as ligand, europium-2,7-dihydroxynaphthalene-3,6-disulfonic acid- Phenanthroline ternary complex {[Eu (HL) (phen) (H2O)] (H2O) 3} ∞; using complexes not involved in the coordination of -OH as the active group, dibutyltin dilaurate As a catalyst, was reacted with isophorone-diisocyanate having an active group -NCO to prepare a europium ternary complex-urethane acrylate luminescent material. The composition, structure, thermal stability and luminescent properties of the complexes and luminescent materials were determined by single crystal X-ray diffraction, infrared, thermal analysis and fluorescence spectroscopy. The results showed that at 496 nm, the complex and the luminescent material can emit strong characteristic fluorescence at 610 nm, and with the increase of the content of the complex, the fluorescence performance is enhanced and no fluorescence quenching occurs in the test range Phenomenon, is a potential application of new luminescent materials.
