xylene spacer) has been synthesized for recognition of dicarboxylicacids. Binding studies have been performed by UV–vis method by varying the chain length of dicarboxylicacids. The downfield chemical shift of amine protons of receptor in presence of adipicacid or glutaric acid and the 1:1 dimeric crystalstructure of the receptor and adipicacid reveal the strong binding interaction.Graphical abstract
