A New Molecular Receptor Based on Thiophene Congener of Troger's Base: Selective Binding with Aliphatic and Aromatic Dicarboxylic Acids

A new molecular receptor bearing pyridylamino groups was prepared with a thiophene congener of Troger's base as a spacer, and was found to exhibit selective binding toward aliphatic and aromatic dicarboxylic acids, primarily depending on the length of the carbon chain.
