Cesium- and rubidium-selective redox-active Bis(calix[4]diquinone) ionophores

The length of the bridging alkylene chain between two calix[4]diquinone moieties determines the selectivity of the receptors for Group 1 metal ions. These redox-active receptors exhibit remarkable selectivity preferences and substantial electrochemical recognition effects towards Cs+ and Rb+ ions. T...

Özet:The length of the bridging alkylene chain between two calix[4]diquinone moieties determines the selectivity of the receptors for Group 1 metal ions. These redox-active receptors exhibit remarkable selectivity preferences and substantial electrochemical recognition effects towards Cs+ and Rb+ ions. The solid-state crystal structure of the Cs+ complex of a bis(calix[4]diquinone) derivative is shown (green: Cs+, red: oxygen).
