Synthesis and cyanide anion recognition of a new displacement fluorescence chemosensor based on two-branched aurone
A new fluorescence turn-on chemosensor based on two dipyridylamine groups substituted aurone moiety, 4?-2,2?-dipyridylamine-3-2,2?-dipyridylamine aurone (1), was synthesized. The recognition properties of the compound for cyanide anions and copper ions were investigated. Yellow fluorescence of the compound is almost quenched completely because of the complexation between the compound and copper ions. After the subsequent addition of cyanide anions, fluorescence spectrum is recovered to the original status of the compound owing to the strong bonding ability between cyanide anions and copper ions and the removal of copper ions from the complexes. The recognition also can be observed by naked eye. The compound exhibits a good reversibility and can be used repeatedly to recognize cyanide anions for several times.
