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 .
