有关苯并15-C-5以及苯基4位引入不同取代基后对金属离子配位性能的研究报道较多。本文为探讨苯环上引入乙酰基后冠醚的络合性能、羰基在环外是否参加配位以及SCN~-对稀土离子配位的影响,合成了4-乙酰基-B-15-C-5与RE(SCN)3·nH_2O(RE=La、Nd、Er、Y)的配合物,并进行了元素分析、IR、UV光谱、摩尔电导、X射线粉末衍射和DTA等分析测试研究。 There are many reports on the coordination properties of metal ions after the introduction of different substituents on benzo 15-C-5 and 4-phenyl. In order to investigate the complexation of crown ether on the introduction of acetyl group on benzene ring, the effect of carbonyl on the coordination of rare earth ions and the coordination of SCN ~ - on the coordination of rare earth ions, the synthesis of 4-acetyl-B-15-C- 5 and RE (SCN) 3 · nH2O (RE = La, Nd, Er, Y) were synthesized and characterized by elemental analysis, IR, UV spectra, molar conductance, XRD and DTA.
