Abstract
Bis-crown-ether derivatives having such configuration that the two crown rings may easily overlap spatially, holding a potassium or the like ion between them, and ion-selective membranes used for said bis-crown-ether derivatives as neutral carrier, which are useful as an ion sensor and are superior to the ion-selective membrane containing valinomycin.
