摘要: 本文报导了Tb,Eu,La与邻氨基苯甲酸(o-AA)或N-苯基邻氨基苯甲酸(N-PAA)及邻菲啡啰啉(Phen)形成的固态三元配合物。通过元素分析,热谱分析和摩尔电导测定确定该类配合物的组成为Ln(Phen)(L)3(Ln=Tb、Eu、La,L=o-AA或N-PAA),考察了这类配合物的红外光谱、UV吸收光谱、核磁共振谱和x光电子能谱,确定其配位形式,并讨论了它们的发光性质。

Abstract: Six solid ternary complexes of Ln(Ⅲ) (Tb, Eu, La) with o-aminobenzoic acid (o-AA)or N-phenylanthranilic acid (N-PAA) and 1, 10-phenanthroline (Phen) were prepared. Thecomplexes have the compositions Ln (Phen) (o-AA)3 or Ln (Phen) (N-PAA)3 and were characte-rized by elemental analysis, IR, UV, molar conductance, 1H NMR, XPS spectra measurements and thermal analysis.Detailed discussion on the luminescence of the complexes is given.
