Anion recognition through hydrogen bonding: a simple, yet highly sensitive, luminescent metal-complex receptor

A new luminescent rhenium(I) polypyridyl-based receptor for a variety of inorganic anions has been designed and synthesized and this artificial receptor shows high affinities for halides, cyanide

Selective turn-on fluorescence detection of cyanide in water using hydrophobic CdSe quantum dots.

The ability of 2,2'-bipyridine-bound copper(ii) ions to quench the photoluminescence of hydrophobic CdSe quantum dots is used to create a novel, selective turn-on fluorescence cyanide sensor.

Fluorescent chemodosimeter for selective detection of cyanide in water.

A coumarin-based fluorescent chemodosimeter with a salicylaldehyde functionality as a binding site has been developed for selective detection of cyanide anions over other anions in water at

Visual detection of cyanide through intramolecular hydrogen bond

An azo compound based on salicylaldehyde displays a red color upon binding to the cyanide anion with micromolar sensitivity. The high affinity is caused by an intramolecular hydrogen bond of phenol

Dipyrrole carboxamide derived selective ratiometric probes for cyanide ion.

Two anion probes 1 and 2 featuring the dipyrrole carboxamide moiety for anion recognition have been prepared and display great selectivity for the cyanide anion over other common inorganic anions in semiaqueous environment via the formation of cyanohydrin derivatives.

A monostyryl-boradiazaindacene (BODIPY) derivative as colorimetric and fluorescent probe for cyanide ions.

A novel boradiazaindacene derivative to detect cyanide ions in solution at micromolar concentrations is developed and displays a large decrease in emission intensity and a reversible color change from red to blue on contact with cyanide ion.

Ion pair recognition by Zn-porphyrin/crown ether conjugates: visible sensing of sodium cyanide.

Synthesis and complexation behavior of ditopic neutral receptors composed of both a Lewis-acidic binding site and aLewis-basic binding site are reported; the receptors bound only NaCN in a d itopic fashion with a color change, and in contrast other sodium salts bound to the receptors in a monotopic fashion without a colorchange.
