以二苯甲酰甲烷(DBM)为第一配体,1. 10-邻菲罗啉(phen)为第二配体,合成了稀土铽配合物,并通过红外、核磁、元素分析和质谱等手段对配合物进行了表征。 在一定条件下,将此稀土配合物加入甲基丙烯酸(MAA)和苯乙烯(St)聚合体系中进行聚合,制备了一种高分子复合材料,并对高分子材料进行了紫外、荧光、热重(TG)分析。 结果表明:这种材料的分解温度大于 220 ℃ ;在 350 nm 和 262 nm 处有较强的紫外吸收;其荧光光谱发出较强的稀土 Tb3+特征吸收峰。 研究表明,所得的高分子复合材料具有较好的紫外吸收性和较高的热稳定性,阻燃实验证明,平均碳化度为 9. 7 cm,说明所得高分子复合材料具有较好的阻燃性。

Terbium rare earth complex has been synthesized with dibenzoylmethane(DBM) as the first ligand, 1,10 -phenanthroline(phen) as the second ligand and was characterized by means of IR spectrum, 1HNMR, elemental analysis and MS spectra. The polymer composites has been prepared by addition terbium rare earth complex to polymerization system of MMA-St under certain conditions and was analysed by UV-Vis spectrum , fluorescence spectra and thermogravimetry(TG). The results showed that the material has the higher decomposition temperature ( 220 ℃ ), the stronger UV absorption in 350nm and 262nm. The fluorescence spectra of the material shows characteristic absorption peaks of Tb3+. Research indicates that the polymer composites has the higher thermal stability and the stronger UV absorption. The flame retardant experiment indicated the average degree of carbonation is 9. 7cm which suggests the polymer composites has better flameproofing.
