摘要：

A new alpha,beta-unsaturated nitro group and coumarin conjugate-based fluorescent chemodosimeter 1 was developed for the selective detection of cyanide anions. The chemodosimeter has shown a selective and sensitive response to cyanide anions over other various anions through a nucleophilic aromatic substitution reaction of the cyanide to 1. When cyanide anions were added, the enhanced fluorescence intensity as well as the color changes of 1 was observed so that micromolar concentrations of cyanides were detectable by the naked eye.
