The kinetics of complexation of the Cs ion with the ligands dibenzo-21-crown-7 (DB21C7) and dibenzo-24-crown-8 (DB24C8) were studied in acetone and in methanol solutions by cesium-133 NMR. In all systems, the predominant mechanism of exchange between the solvated and complexed Cs ion sites is the bimolecular process. The kinetic parameters for the exchange have been determined. With both crown ethers, the free energy barrier for the exchange process appears to be independent of solvent. 12 references, 2 figures, 2 tables.
