  • Title: Rational design of a dual chemosensor for cyanide anion sensing based on dicyanovinyl-substituted benzofurazan.
    Author: Liu Z, Wang X, Yang Z, He W.
    Journal: J Org Chem; 2011 Dec 16; 76(24):10286-90. PubMed ID: 22088170.
    Abstract:
    A dicyanovinyl-substituted benzofurazan derivative (C1) was prepared as an efficient ratiometric chemosensor for cyanide anion detection in aqueous acetonitrile solution. Mechanism studies suggested that the nucleophilic addition of cyanide to the α-position of the dicyanovinyl group blocked the ICT progress of C1 and induced remarkable emission and absorption shift.
