Syntheses, Structures and Photophysical Properties of a Series of Sm3+Coordination Complexes
摘要
Abstract
Four new Sm3+ coordination complexes, {[SmZn(2,5-pdc)2(tpha)0.5(H2O)]·2H2O}n(1), [Sm2Zn2(C6H5 COO)10(Imh)2(H2O)2] (2), {[Sm2(NO2C6H4COO)6(H2O)4] ·H2O}n(3) and{[SmN(CH2COO)3(H2O)2]·H2O}n(4) [ 2, 5-pdc = pyridine-2, 5-dicarboxylate, tp = p-phthalate, C6 H5 COO=benzoate, Imh=imidazole, NO2 C6 H4 COO=p-nitrobenzoate, N ( CH2 COO ) 3=nitrilotriacetate ] , were synthesized by hydrothermal method. Their structures were determined by single-crystal X-ray diffraction. At room temperature, the IR, UV-Vis-NIR and emission spectra of the four complexes were measured and ana-lyzed. The four complexes exhibit the characteristic emission bands of the Sm3+ ion in the visible or NIR region, which should be attributed to the sensitization from the Zn-ligand( d-block) and ligands after forming coordination complexes. In addition, the sensitization from different ligands and d-block to Sm3+ ion was dis-cussed, the shift, split and broad of the NIR emission bands were analyzed.关键词
