POSS基功能化(铕)配合物的合成及性能研究

Coordination Assembly and Characterization of Rare Earth( Eu)Complexes Covalently Bonded to POSS

杂化配体POSS-Si-ACAC可以用巯基多面体低聚倍半硅氧烷(POSS-SH)修饰β-二酮类配体乙酰丙酮(ACAC)通过共价键和来得到,再将稀土溶液Eu(NO3)3和Tb(NO3)3分别加入进去得到稀土二元杂化材料Eu-(POSS-Si-ACAC)3和Tb-(POSS-Si-ACAC)3。再加入聚甲基丙烯酸甲酯(PMMA)可以得到稀土三元杂化材料,我们研究杂化材料的热稳定性和荧光性能得出结论,三元杂化材料的热稳定性和荧光性能都能得到提高。

With the sulfhydryl polyhedral oligomeric silsesquioxane（ POSS- SH） modified β- diketone ligand acetylacetone（ ACAC）,covalent bonding hybrid ligand POSS- Si- ACAC was synthesized. The rare earth solution of Eu（ NO3）3and Tb（ NO3）3were added in to obtained binary lanthanide organic / inorganic hybrid material Eu-（ POSS- Si- ACAC）3and Tb-（ POSS- Si- ACAC）3; The ternary hybrid materials were obtained by adding the polymethyl methacrylate（ PMMA）. The thermal stability and luminescence properties of hybrids were investigated and found that the ternary hybrid materials exhibited better thermal stability and stronger emission intensity.
