Studies on Rare Earth Complexes with Crown Ether (ⅩⅩⅣ)——Synthesis and Characterization of Complexes of Lanthanide Isothiocyanates with Dibenzo-30-crown-10

摘要

Introduction The study of metal complexes with the crown ether is a quite interesting research field, but the research has mainly focused on the metal complexes with some crown ethers with a relatively small cavity such as 12-crown-4, 15-crown-5 and 18- crown-6 as well as their derivatives. Crown ethers with a larger cavity contain more oxygen atoms, so they have the ability to form the complexes of a higher co-
