Abstract: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 1 H, 13 C 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 showed no evident binding with Cl -, Br … Show more
In this communication, a new cyanide (CN−) ion selective chromogenic receptor (L) was developed by reacting 2,4-dinitrophenylhydrazine with 2,3,4,5-tetraphenylcyclopenta-2,4-dienone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
