Different electrically neutral lipophilic di‐ and triamides were prepared and their ion selectivity in membranes studied. In membranes the ionophore N , N′ ‐diheptyl‐ N , N′ ‐dimethyl‐succinamide prefers Ca 2+ over Mg 2+ by a factor of 20 but rejects Na + and K + in respect to Mg 2+ by a factor of 100 and 10, respectively. This selectivity suffices to perform useful intracellular Mg 2+ activity studies.
