(Figure Presented) Acid-specific conformational changes: Protonation of meso-aryl-substituted rubyrin 1 with HCl or CF3CO2H 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; CF3CO2-: red shift). The distinct counteranion-dependent color changes upon addition of the acids to the "anion sensor" 1 are easily detected.
