英文摘要：

The compound, 3＇,6＇-bis（tetramethylethylenedioxyboryl）fluorane, synthesized in this experiment is a kind of H2O2 fluorescence-strengthened reagent, which depends on deprotection mechanism and can examine the H2O2 concentration sensitively. The structure of the compound was confirmed by the IR and ^1H NMR spectra. The influences of reaction time, solvent and base on the probe synthesis were investigated in detail. The response time of the fluorescent probe was also studied and as a result, the optimal time for the H202 detection is 3 min. The fluorescence intensity of the probe was gradually increased with the increase of H202 concentration in the range of 2.3-10^-12～2.0×10^-8 mol/L, the detection limit of H2O2 was 2.3×10^-12 mol/L, and the recovery rates in the blood serum were in the range of 93.9%～102.2%.
