A new series of crowned sulfonylhydrazone derivatives 3a3h have been synthesized by condensation of aromatic aldehydes with (benzo-15-crown-5)-4'-sulfohydrazide (2) and characterized by elemental analysis, IR, 1H NMR, 13C NMR and MS spectra. Compound 2 was synthesized from benzo-15- crown-5 via sulphonation and hydrazinolysis. The UV-Vis data indicated that the receptors 3d, 3e and 3h bearing phenolic hydroxy groups can act as selective sensors for basic anions.

Key words: benzo-15-crown-5, sulphonation, recognition, crown ether
