| 摘要: 用分光光度法对镧系离子(Nd3+,Ho3+,Er3+)与1-苯基-3-甲基-4-三氟乙酰基吡唑酮-5(PMTFP)和二安替吡啉甲烷(DAM)水-乙醇溶液体系的研究以及对制备钕的相应配合物的元素分析证实:形成的三元配合物的的组成比为Ln3+:PMTFP:DAM=1:3:1。计算了相应配合物超灵敏跃迁的光吸收振子强度,并图示了它们之间的线性关系。研究了固态钕的三元配合物的红外吸收光谱和热稳定性。 镧系离子(Ln3+)同DAM和1-苯基-3-甲基-4-苯甲酰基吡唑酮-5(PMBP)等β-二酮以及Ln3+与PMTFP和三辛基磷氧化物(TOPO)的三元配合物的研究已有报导。本文报导了Ln3+(Nd3+、Ho3+、Er3+)-PMTFP-DAM体系中的超灵敏跃迁现象与配位作用,以及Nd(Ⅲ)-PMTFP-DAM配合物的合成、组成和性质。 |

| Abstract: In this paper, the ternary coordination compounds of lanthanides ions (Nd3+, Ho3+, Er3+) with l-phenyl-3-inethyl-4-trifluroacetyl-pyrazolone-5 (PMTFP) and diantipyryl methane (DAM) in water-ethanolic solution have been studied by spectrophotometry. Using the methods of continuous -variation and equilibrium shift, we have shown that in ternary coordination compounds, the ratio of components is Ln3+:PMTFP:DAM = 1:3:1.The oscillator strengths (P) of absorption bands of hypersensitive transition of Nd3+, Ho3+, Er3+ ions and their coordination compounds in water-ethanolic solution have been calculated, and their linear relation, is shown graphically, too.A corresponding ternary coordination compound of neodymium, a yellowish crystal, has been prepared and characterized by elemental analysis and infrared as well as thermogravimetric (TG) and differential thermal analysis (DTA). Its molecular formula is Nd (C12H8O2N2F3)3 C223H24O2N . |
