Abstract

Chromogenic and electrochemical recognition are combined in the calix[4]arenecrown-4 1: 1) Conformational changes upon complexation of Na⁺ or K⁺ influence the through-space exciton coupling between the two diametrically arranged thienylene analogues of p-terphenoquinone used as the chromophores, and a color change results. 2) Complexation also causes an anodic shift in the oxidation and reduction potentials of 1.
