摘要： 制得了高氯酸铕(Ⅱ)与二苯并-18-冠-6(L)生成的固体配合物。经元素分析、X-射线粉末衍射、差热和热重、红外光谱、光声光谱和荧光光谱分析证明为1:1的、未溶剂合的配合物——Eu(ClO4)2·L,呈白色晶状,在日光照射下变为蓝灰色,避光放置又可慢慢复原。

Abstract: The complex of Eu(ClO4)2 and dibenzo-18-crown-6 ( L ) has been prepared in solid state and characterized by elemental analysis, X-ray diffraction, TG-DTA, IR and photoacoustic spectra, as well as fluorescence emission spectra.The complex is proved to be Eu(ClO4)2·L. This complex changes from colourless to a pale blue when irradiated with sunlight, but restores gradually to its original state in the dark.
