A unique near-infrared fluorescent probe based on dual-DNP binding sites for rapid monitoring of hydrogen sulfide in food samples and living cells

A new NIR fluorescent probe (DCIQ-2DNP), which combined the thiolysis of dinitrophenyl (DNP) ether and DNP-marked electron-deficient quaternary carbon, was reported for the first time for detection of H 2 S. The DCIQ-2DNP probe showed an NIR emission signal (740 nm), a large Stokes shift (128 nm), a...

Summary:A new NIR fluorescent probe (DCIQ-2DNP), which combined the thiolysis of dinitrophenyl (DNP) ether and DNP-marked electron-deficient quaternary carbon, was reported for the first time for detection of H 2 S. The DCIQ-2DNP probe showed an NIR emission signal (740 nm), a large Stokes shift (128 nm), and rapid monitoring of hydrogen sulfide (within 60 s) in food samples and living cells.
