Abstract
Several trans-cyclohexano crown ethers have been synthesized and studied as sensor materials for different metal cations in PVC-matrix membranes of ion-selective electrodes. The potentiometric selectivity of the membranes has been found to correlate with the chemical structure peculiarities of the incorporated compound and can be changed by variation of the substituent attached to the cyclohexane fragment. Some of the compounds show superior selectivity for potassium over many other metal cations.
