Thirty-three new tetrakis rare earth chelate salts of the type: Piperidinium+ [(Ar-COCH-CO-R)4]−, have been prepared and characterized. Eighteen of these complexes have been examined for their fluorescence properties in solid state at 77°K. Correlations have been drawn between the fluorescence spectra and the possible site symmetries of the Eu3+ ion in europium tetrakis chelates. The i.r. of eighteen
已经制备和表征了33种新的四烷基稀土螯合物盐:哌啶鎓+ [(Ar-COCH-CO-R)4 ] -。已经检查了这些复合物中的18种在77°K固态下的荧光性质。已经在四ki化ates螯合物的荧光光谱和Eu 3+离子的可能位点对称性之间绘制了相关性。已经研究了18个配合物的ir,特别是参考了四配位体的结构考量。还讨论了Ar和R对拉伸频率和拉伸频率的影响。
