- ... 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 ...

- ... A novel ratiometric fluorescent probe for palladium species was synthesized based on an allyl carbonate group, a novel reaction site, and a hemicyanine dye. The probe displays relatively rapid response, high selectivity, and anti-disturbance toward palladium in HEPES buffers without additional reagents. The detection mechanism, palladium triggers the cleavage of allyl carbonate in the probe and th ...
