Synthesis and fluorescent properties of Sm(Ⅲ) complexes with 1,3-diphenyl-4-benzoyl 5-pyrazolones
【摘要】 合成了钐 ( )的 1,3-二苯基 - 4 -苯甲酰基 - 5 -吡唑酮 (DPBZP)的二元配合物 Sm(DPBZP) 3· 2 H2 O和三元配合物Sm(DPBZP) 3· Phen(Phen为邻菲啉 ) ,通过化学分析和元素分析确定了配合物的组成 ,通过 FT- IR谱对配合物进行了表征。配合物的荧光光谱表明 ,配合物发射 Sm( )的特征荧光 ,1,3-二苯基 - 4 -苯甲酰基 - 5 -吡唑酮的三重态能级与Sm3+ 最低激发态 4 G5/2 能级具有良好匹配 ;第二配体 Phen具有荧光增强作用。
【Abstract】 The binary and ternary Sm(Ⅲ) complexes with the 1,3 diphenyl 4 benzoyl 5 pyrazolones(DPBZP) and 1,10 phenanthroline(Phen) have been prepared.The composition of the complexes was determined to be Sm(DPBZP) 3·2H 2O and Sm(DPBZP) 3 Phen by chemical and elementary analysis.Their structures were further characterized by FT IR spectra.The fluorescence spectra of the complexes showed characteristic fluorescence of Sm(Ⅲ).The energy level of the triplet state of DPBZP ligand match well with the lowest excited state ( 4G 5/2 )level of Sm 3+ ion.The second ligand Phen showed enhancement effect on the fluorescence of the complexes.
【Key words】 Sm(Ⅲ); 1,3 diphenyl 4 benzoyl 5 pyrazolone; complex; fluorescence;
