A Dual-Mode Colorimetric and Fluorescent Sensor for Rapid Detection of Cyanide Ions: Rational Design, Interaction Studies, and Practical Applications
A calix[4]arene-based fluorescent chemosensor containing two quinolinium units (C4-BisQ) was synthesized and evaluated for the selective detection of cyanide (CN−). C4-BisQ showed a dual-mode optical response with a green-to-blue color change under ambient light and fluorescence quenching upon CN− addition in CH3CN/H2O...
