摘要

Abstract: Crown-4 derivatives of 13-through 16-member rings bearing a long aliphatic chain have been synthesized in an effort to obtain highly selective ionophores for lithium ions. The measurements of potentiometric selectivity coefficients for polymeric membranes containing the crown ethers indicated that their lithium selectivities can be explained primarily in terms of the size-fit concept, the 14-crown-4 and 15-crown-4 derivatives being much more ...
