Abstract: Ion-selective membranes are disclosed which are suitable for use in ion-selective sensors. The membranes include a mercuracarborand ionophore. Exemplary ion-selective membranes include Mercuracarborand-3 as the ionophore which is incorporated within a polymer matrix. The ion-selective membranes may be used in a wide variety of ion sensors including ion-selective membrane electrodes.
