Acid‐specific conformational changes : Protonation of meso ‐aryl‐substituted rubyrin 1 with HCl or CF 3 CO 2 H causes different conformational changes, as revealed by specific shifts in the UV/Vis absorption bands relative to those of the free‐base form (Cl − : blue shift; CF 3 CO 2 − : red shift). The distinct counteranion‐dependent color changes upon addition of the acids to the “anion sensor” 1 are easily detected.
