Paragraph 00332-0034, (2017/01/17)
The invention belongs to the field of organic chemistry, and particularly relates to a substitution coumarin-pyridine derivative, a preparing method thereof and an application thereof. The structural formula of the substitution coumarin-pyridine derivative is shown as the first formula (please see the specification). In addition, the invention provides the preparing method of the compound and the application of the compound to detection of endogenous SO2 in living cells. The substitution coumarin-pyridine derivative has the advantages of being good in water solubility, high in SO2 selectivity, low in detection limitation, small in toxicity, high in quantum yield, large in Stokes shifting, mild in overall reaction condition, low in cost, capable of achieving detection of the endogenous SO2 in the living cells and the like at the same time; the defects that as for an existing SO2 detection small-molecular fluorescent probe, organic solvents need to serve as cosolvents, and the quantum yield is low are overcome, and a new choice is provided for detecting the endogenous SO2 in the living cells.
