| 摘要: 本文合成了单硫代二苯甲酰甲烷(HTDBM)和三价希土离子及路易斯碱(Q)的Ln(TDBM)4QH型配合物(Ln=除Ce外的La～Lu,Q=二乙基胺).测定了它们的摩尔电导值、红外光谱,可见—紫外光谱,核磁共振谱.观察到配合物是通过硫原子、氧原子同时与Ln3+离子配位.Ln-O键强于Ln-S键.在Nd3+、Pr3+、Ho3+、Er3+离子的该类配合物的可见吸收光谱中发现超灵敏跃迁现象.讨论了题述配合物作为核磁共振化学位移试剂的可能性. |

| Abstract: Ln(TDBM)4QH(where Ln=La-Lu, except Ce; Q=(C2H5)2NH)chelates have been prepared. The elemental analysis, molar conductivities, IR-spectra, electronic spectra and NMR-spectra have been investigated. The lanthanide ions are coordinated through S atom and O atom. The Ln-O bond is stronger than Ln-S, which is proved by IR-spectra. The phenomena of hypersensitivity arising from Pr3+、Nd3+、Ho3+、Er3+ coordination compounds in acetone also have been studied. Possibility of use for NMR-chemical shift reagent have been confirmed. |
| Keywords: lanthanide complex hypersensitized transition Ln-S bond NMR-chemical shift reagent |
