Abstract
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.

Claim 4
Dependent Claim
92 words
A bis-crown-ether derivative of Claim 2 in which the group Y in the sub-formula (II) is a group represented by the formula: or (in which R 1 and R 2 each represents a hydrogen atom or an alkyl group of C1 - C 20 , p and q each represents O or an integer of 1, 2 or 3, R 3 and R 4 take mutually cis-configuration and each represents a halogen atom, a lower alkyl group or an aryl group, and the two bonds of the cyclohexylene group are at cis-position)
Claim 5
Dependent Claim
48 words

7 . A bis-crown-ether derivative of Claim 1 represented by the general formula (VI): (in which Z represents a group -CH 2 0-CO-, -CO-O-, -CH 2 0- or -CONH-, provided that the two bonds in the cyclohexylene group are at cis-position).
Claim 9
Dependent Claim
47 words
A bis-crown-ether derivative of Claim 1 represented by the formula (VII): (in which Z represents a group -CH 2 0-CO-,-CO-O-, -CH 2 0-or -CONH-, and R 3 and R 4 take mutually cis-configuration and each represents a halogen atom, a lower alkyl group or an aryl group).
