摘要： 合成并表征了一系列铽与含不同个酰代-的1-苯基-3-甲基-吡唑啉酮-5的三元配合物Tb(L)3·2H2O和Tb(L)3·Dipy[L＝1-苯基-3-甲基-4乙酰基吡唑啉酮-5(PMAP),1-苯基-3-甲基-4-丙酰基吡唑啉酮-5(PMPP),1-苯基-3-甲基-个异丁酰基吡唑啉酮-5(PMIBP),1-苯基-3甲基-4-特戊酰基吡唑啉酮-5(PMPVP),1-苯基-3-甲基-4-苯甲酰基吡唑啉酮-5(PMBP),Dipy＝2,2'联吡啶].用频域法测定了它们在溶液中的荧光寿命.结果表明,4-烷基酰代吡唑啉酮-5配合物的荧光强度比4-苯甲酰基吡唑啉酮-5配合物强3个数量级.

Abstract: Aseries of terbium ternary complexes with 4-acyl substituted pyrazolones:Tb(L)3. 2H2Oand Tb(L)3. Dipy, where L=1-phenyl-3-methyl-4-acetyl-5-pyrazolone (PMAP ), 1-phenyl-3-methyl-4-propionyl-5-(PMPP), 1-phenyl-3-methyl-4-isobutyryl-5-pyrazolone (PMIBP), 1-phenyl-3-methyl-4-pivaloyl-5-p (PMPVP) and 1-phenyl-3-methyl-4-benzoyl-5-py (PMBP ), Dipy=2, 2'-dipyridyl, were synthe-sized and identified by elementary analysis. The complexes were characterized by FT-IR,UV-Vis spectra and TG-DTAanalysis. The luminescences from both the solid state and so-lution were studied and their fluorescence lifetime was determined by using the frequency-do-main method. The results show that both fluorescence intensities and lifetime of these com-plexes strongly depend on the structure of the substituted 4-acyl groups. The fluorescence intensities of the alkyl acyl substituted pyrazolone terbium complexes are three orders magni-tude stronger than that of Tb (PMBP)3 2H2O, and the introduction of the neutral ligand (Dipy) can enhance the fluorescence intensities of the complexes
