制备了一种用于乙腈水溶液中氰基阴离子检测的比率化学传感器。机理研究表明，氰化物在二氰基的α-位上的亲核加成阻碍了c1的ICT进程，并引起了显著的发射和吸收位移。
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 alpha-position of the dicyanovinyl group blocked the ICT progress of C1 and induced remarkable emission and absorption shift.
