摘要
4-酰代双吡唑啉酮是一类新型β双酮多啮金属离子螫合剂和萃取剂,其性能优于单吡唑啉酮。本文继合成1,5-双(1′-苯基-3′-甲基-5′-氧代吡唑-4′)-1,5-戊二酮(BPMPPD,H_2A)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。
Fourteen new solid complexes of rare earth RE_2A_3P_2·nH_2O [RE=Y, La, Pr, Nd,
Sm-Lu; H_2A=1, 5-bis (1'-phenyl-3'-methyl-5'-pyrazolone-4'-)-1, 5-pentanedione
(BPMPPD) and P=1, 10-phenanthroline, n=4 for Y, La; n=2 for other RE] have been
synthesized and characterized by elemental analyses and ligand analyses. The IR, UV-
visible spectra, fluorescence spectra and DTA-TG curves of these complexes were recorded
and discussed. The fluorescence quantum yield of Sm, Tb complexes were measured.
