| 摘 要： | 采用水热方法合成了4种Sm3+配合物, 即{[SmZn(2,5-pdc)2(tp)0.5(H2O)]·2H2O}n(1), [Sm2Zn2(C6H5COO)10(Imh)2(H2O)2](2), {[Sm2(NO2C6H4COO)6(H2O)4]·H2O}n(3)和{[SmN(CH2COO)3(H2O)2]·H2O}n(4)[2,5-pdc=2,5-吡啶二羧酸根, tp=对苯二甲酸根, C6H5COO=苯甲酸根, Imh=咪唑, NO2C6H4COO=对硝基苯甲酸根, N(CH2COO)3=氨三乙酸根]. 通过单晶X射线衍射确定了其晶体结构. 在室温下测定了其红外光谱、 紫外-可见-近红外光谱以及在近红外区和可见区的发射光谱. 结果表明, 4种配合物在近红外区或可见区均出现Sm3+离子的特征发射. 这是形成配合物后, Zn-配体部分和配体对Sm3+离子发光的敏化作用所致. 此外, 讨论了不同有机配体或d过渡金属离子对Sm3+离子发光的影响, 并分析了配合物中Sm3+离子的近红外发射带位移、 劈裂和加宽的原因.

| Abstract: | Four new Sm3+ coordination complexes, {[SmZn(2,5-pdc)2(tpha)0.5(H2O)]·2H2O}n(1), [Sm2Zn2(C6H5COO)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, C6H5COO=benzoate, Imh=imidazole, NO2C6H4COO=p-nitrobenzoate, N(CH2COO)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 analyzed. 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 discussed, the shift, split and broad of the NIR emission bands were analyzed. |
