Anion-complexing compound, method for the preparation thereof, an ion-selective membrane as well as a sensor provided with such a compound or membrane.

摘要

The invention is directed to an anion-complexing compound with the formula Iwherein R1 is a six-membered ring, Y' is -NHC(X)NH-, and Y'' is selected from the group consisting of -NHC(X')-, -C(X')NH-, and -NHC(X') NH-; and wherein X and X', independently of one another, is a sulphur or oxygen atom. R4 and R4' are either identical represented by a variety of groups or together represent a group such that the compound has a macrocyclic structure. The invention is also directed to a method of preparing such a compound, an ion-selective membrane, as well as a sensor provided with such a compound or membrane.
