Abstract
A new type of bis(crown ether)s containing 15-crown-5 and monoaza-18-c rown-6 actively transported Na+ and K+ in opposite directions across a dichloromethane membrane by pH control. The effect of the structure o f the ion carriers on their transport abilities was examined. A key po int for the molecular design of the carriers is how to give them compl exing ability toward Na+ under acidic conditions. A proper choice of t he transport conditions was found to be essential for the success of t he double uphill transport.
