| 摘 要： | 在296和77K测定了四(二苯甲酰甲烷)合铕酸二乙铵(C2H5)2NH2Eu(DBM)4]的高分辨激发光谱和荧光光谱。光谱数据说明在77K, 配合物含有五种Eu(III)格位。详细分析发光光谱说明, 由于配合物中配位体里的苯基错位产生不同的构型, 形成了不同的Eu(III)物种, 显示出不同的晶体场效应, Eu(III)离子的这种灵敏性可以作为晶体构型探针。

| Abstract: | High-resoln. excitation and luminescence were measured at 296 and 77 K. Eu3+ sites of Et2NH2+Eu(Bz2CH)4- were probed. The 5D0?F0 excitation spectrum of the complex displays 3 max. at room temperature and splits into 5 max. at 77 K. A series of similar spectra arise from slightly unequiv. Eu(Bz2CH)4- moieties differing in the disorder of Ph rings, experiencing slightly different crystal field effects. This shows the sensitivity of Eu3+ as conformational probe in the solid state. |
