A chemical probe capable for fluorescent and colorimetric detection to Cu2+ and CN− based on coordination and nucleophilic addition mechanism

A salamo-like chemical probe HL with novel structure for continuous recognition of Cu2+ and CN− was synthesized by Schiff base reaction. Some meticulous researches on the properties of probe HL had been carried out by UV–Vis spectra and fluorescence spectra, high-resolution mass spectra and nuclear magnetic resonance spectra. The probe HL could identify Cu2+ by dual channels, and the formed copper(II) complex L-Cu2+ could be used as a probe to...
