Abstract

Abstract: Triphenylamine‐based fluorescent open and macrocyclic receptors1 and2 have been designed and synthesized for the recognition of linear aliphatic dicarboxylates of varying chain lengths. o ‐Phenylenediamine in the form of an amide has been utilized as the binder of carboxylate. The binding behavior was studied in polar solvents using 1 H NMR, fluorescence and UV‐vis spectroscopic methods. Binding takes place at the charge neutral binding sites of the receptors with concomitant change in emission. The open structure1 exhibited selectivity for long chain dicarboxylates while good selectivity for glutarate was achieved in the case of macrocycle2 .Theoretical studies on both1 and2 itself and their complexes with dicarboxylates have been done in details.
