Özet

A new receptor named, 2‐(2‐(2,4‐dinitrophenyl)hydrazono)2H‐indene‐1,3‐dione,used as a

colorimetric sensor based on 2,4‐dinitrophenylhydrazone derivative of ninhydrin was

synthesized by simple step with good yields and characterized by IR and 1H, 13C NMR and MS

spectroscopic techniques. The anion recognition properties were studied by UV‐Vis

spectroscopic technique. The results showed that the receptor had a higher affinity to F‐, CN‐,

H2PO4‐, CH3COO‐ and OH‐, but shows no evident binding with Cl‐, Br‐ and I‐. Binding of the

reseptor to anions such as CN‐, AcO‐, F‐, H2PO4‐ and OH‐exhibited an obvious color change from

greenish yellow to purplish blue, which was possible to observe by the naked eye.
