Several molecules based upon 1,3,5-triaxially substituted cyclohexane templates have shown promising results as ionophores. More importantly, in the case of Li⁺, cyclohexane is a more selective ionophore than the traditional 12-Crown-4 macrocyclic ether. In order to understand the effect of the alkali metal ion binding to cyclohexane, the infrared spectra of Li⁺, Na⁺, and K⁺ ions complexed with cyclohexane were recorded in C-H stretching region. The effect of the ion binding on the C-H stretching vibrations will be discussed.
