稀土冠醚配合物是引起人们广泛兴趣的研究领域。以往的研究工作中所涉及到的配体大都是分子中只含有一个冠醚环的单冠醚化合物,相对单冠醚配体而言,双冠醚配体中的两个冠醚环单元由于在一定条件下能产生协同作用,因而双冠醚配体对于某些金属离子具有更好的配位性能和选择性。我们在过去对三价及非三价稀土单冠醚固态配合物的合成和性质研究基
Rare earth crown ether complex is a field of interest that has attracted widespread interest. Most of the ligands involved in the previous research work are single-crown-ether compounds containing only one crown ether molecule in the molecule. The two crown ether ring units in the double crown ether ligand Under certain conditions can produce synergies, so double crown ether ligand for some metal ions have better coordination properties and selectivity. We have in the past on the trivalent and non-trivalent rare-earth single-crown ether solid state complex synthesis and properties of
