Rational design, green synthesis of reaction-based dual-channel chemosensors for cyanide anion

Chemosensors CF1–CF3 were designed and synthesized via a simple green chemistry procedure. CF3 could instantly detect cyanide anion in aqueous solution by dual-channel model. The detection limit of CF3 for CN- is 10 nM. Test strips based on CF3 could act as a convenient and efficient CN− test kit.
