Discrimination of isomeric anions : The selective, shape‐controlled colorimetric sensing of dicarboxylate ions has been achieved and represents a development in the “naked‐eye” detection of certain organic isomers. The photograph shows the diverse colors of solutions of a 1,3,5‐triarylpent‐2‐en‐1,5‐dione in dioxane/water solution (70:30 v/v) at approximately pH 6, in the presence of either maleate ( cis isomer, magenta) or fumarate ( trans isomer, yellow) ions.
