Abstract
A fluorescence probe (HBM) based on conjugation of 3â²-formyl-4â²-hydroxy-4-biphenylcarbonitrile to 2,4-dinitrophenylhydrazune for the detection of hypochlorite has been developed. The probe exhibited a highly sensitive and selective response toward hypochlorite (ClOâ) with a low detection limit of 49â¯nM. The sensing mechanism was considered that the hypochlorite triggered oxidative hydrolysis of probe HBM and the cyanobiphenyl fluorophore was released, which also have been evidenced by the MS analysis. Most notably, the response time of the probe HBM to the OClâ is only a few seconds. The probe was also successfully applied to fluorescence imaging of OClâ in the living cells.
