Abstract
Cis- and trans-2-phenylcyclohexano-14-crown-4 and cis- and trans-2,3-d iphenylcyclohexano-14-crown-4 were prepared and their ion selectivity was determined by means of extraction of alkali metal picrates, stabil ity constants, and ion-selective electrodes. Cis diphenyl derivative e xhibits the highest lithium ion-selectivity of the four ionophores exa mined, which is as high as that of decalino-14-crown-4, one of the bes t Li+-selective ionophores.
