对合成的30多个络合物的激发光谐、发射光谱、紫外吸收光谱、碳氢分析、差热及热重进行了初步研究。结果表明较好发光材料其羧酸配体一般在235～265nm有较强的紫外吸收;羧酸分子应有给电子的共轭效应;共轭体系上的取代基无论从空间或其性质上均应有利于与Eu~(3+)的络合;或羧酸分子能与Eu~(3+)成较强的整合结构。络合物生成以pH=4～5为宜,一般说来,结晶态的络合物的发光性能较好。 The excitation light harmonics, emission spectra, UV absorption spectra, hydrocarbon analysis, differential thermal and thermogravimetric studies of over 30 complexes were studied. The results show that the better luminescent materials have strong UV absorption at 235-265 nm. The carboxylic acid molecules should have the conjugation effect to the electrons. The substituents on the conjugated system both in space or on their properties Should be conducive to Eu ~ (3 +) complex; or carboxylic acid molecules with Eu ~ (3 +) into a strong integrated structure. Complex formation to pH = 4 ~ 5 is appropriate, in general, crystalline complexes of the better light-emitting properties.
