Coumarin-Imine-Quinoxaline Linkage Designed Based on the Strecker Reaction as a Receptor for Fluorometric Cyanide Anion Detection in Neutral Media
A coumarin-imine-quinoxaline linkage designed based on the Strecker reaction selectively exhibits blue fluorescence on the addition of CN- to an imine moiety at neutral pH. The receptor facilitates rapid (within 5min), selective, and sensitive (detection limit: 1.4 mu M) detection of CN-.
