Abstract
Five new nitrogen-oxygen mixed donor macrocycles have been prepared by condensation of N, N-bis[2-(2-formylphenoxy)ethyl]-4-methylphenylsulphonamide with diamino compounds, followed by a one-pot reduction of the intermediate bis-Schiff base. The transport of alkali metal ions across a liquid membrane using these macrocycles as ion carrier was studied, and the results show that the rates of cation transport are affected by the size of macrocycle.
