The compound 2,2 -(1,4-phenylenebis(methylene)) bis(hydrazinecarbothioamide) was synthesized and its complex with gadolinium was studied as an anion receptor. The binding properties of the receptor with anions were investigated by UV-Vis spectroscopy. The absorption spectra of the receptor in DMSO in the presence of F underwent substantial changes, with appearing a new band at 426 nm and a clear isosbestic point. The UV-Vis spectroscopic titration experiments indicated the formation of 1∶1 complex between the receptor and F. The receptor holds promise to be used as an optical chemosensor with naked-eyes.

Key words: thiourea, Gd(III) complex, anion recognition, UV-Vis absorption spectra, chemosensor
