A novel recognition mechanism supported by experiment and theoretical calculation for hypochlorites recognition and its practical application

• We have developed two new colorimetric and fluorescent probes for hypochlorite based on a novel recognition mechanism: amido oxidized nitroso-group by hypochlorites.
• The optical properties of the probe 2 and its ClO−-addition product were studied based on DFT and TDDFT were explored at the m062x/6-31+G (d) level.
• The probe 2 could be applied in practical applications such as detecting the hypochlorite concentration of sodium hypochlorite disinfectant and bioimagings.

We have developed two new colorimetric and fluorescent probes for hypochlorite based on a novel recognition mechanism: amido oxidized nitroso-group by hypochlorites, which realized the preparation of nitroso compounds. Furthermore, 1H NMR, ESI-MS and theoretical calculation proved the recognition mechanism. In addition, the probe 2 was applied in practical applications such as detecting the hypochlorite concentration of sodium hypochlorite disinfectant and bioimagings.
