Ｖｏｇｔｌｅ等［１］发现，直链醚除具有类似冠醚配位各种金属离子的能力外，还弥补了冠醚的不足之处，如易合成、产率高、价廉等．我们曾报道过有关ＥＰＲ工作［２，３］．本文合成了２，４－二羟基苯甲醛缩二甘醇二胺（ＤＨＹＤＡ）与镧系的新配合物，研究了配合物的１... Vogtle et al. [1] found that, in addition to its ability to coordinate various metal ions like crown ether, linear ethers also make up for the shortcomings of crown ethers, such as easy synthesis, high yield and low cost. We have reported on the work of EPR [2,3]. In this paper, a new complex of 2,4-dihydroxybenzaldehyde diglycol diamine (DHYDA) and lanthanides was synthesized.
