- ... In this study, we synthesized CTB and CB probes based on doubly activated Michael acceptors to selectively detect cyanide (CN−) anions through a one-step condensation reaction of coumarinyl acrylaldehyde with the corresponding derivatives of malonyl urea (thiourea). Through the conjugated addition of CN− to the β-site of the Michael acceptor, both probes displayed colorimetric and fluorometric dua ...
