We have developed crown ether derivative compounds for cesium separation, and furthermore studied the relationship between structure and complexation ability for Cs. In this present study, the developed benzo-crown ethers were simple structures, but relatively high Cs selectivity than K was observed. The DFT calculation result suggested that electron donation from aromatic ring would also enhance Cs selectivity and we are re-considering the model for Cs selectivity. The other coordination properties of these crown ether derivatives with Cs were studied by NMR, UV-Vis spectroscopy and so on, and will be presented in this talk.
