4-酰代双吡唑啉酮是一类新型β双酮多啮金属离子螯合剂和萃取剂, 其性能优于单吡唑啉酮, 本文继合成1,5-双(1'-萃基-3'-甲基-5'-氧代吡唑-4')-1,5-戊二酮(BPMPPD, H2A)后, 又合成了它和1,10-二氮杂菲(Phen, P)与稀土元素形成的三元固态配合物, 并对这些新配合物的性质进行了研究。

关键词: 吡唑酮 P, 三元络合物, 稀土金属络合物, 稀土元素, 酰化合物, 二氮杂菲, 量子效率, β双酮类, 固体络合物

RE2A3L2.H2O [RE = Y, La, Pr, Nd, Sm-Lu; H2A = 1,5-bis(1'-phenyl-3'-methyl-5'-pyrazolon-4'-yl)-1,5-pentanedione; L = 1,10-phenanthroline, n = 4 for Y, La; n = 2 for other Re] were synthesized and characterized by elemental analyses and ligand analyses. The IR, UV-visible and, fluorescence spectra and DTA-TG curves of these complexes were recorded and discussed. The fluoroscence quantum yield of Sm, Tb complexes were measured.

Key words: PYRAZOLONE P, TERNARY COMPLEX, RARE EARTH METAL COMPLEX, RARE ELEMENT, ACYL COMPOUND, PHENANTHROLINE, QUANTUM EFFICIENCY, BETA DIKETONES, SOLID COMPLEX
