The invention discloses a hydrogen peroxide near-infrared fluorescent probe FBMH with large Stokes shift as well as a preparation method and application of the hydrogen peroxide near-infrared fluorescent probe FBMH. The structural formula of the FBMH is as shown in the formula I. The FBMH itself is almost free of fluorescence. When the FBMH and H2O2 coexist, the system has a fluorescence emission peak at 670nm. The fluorescence of the system is gradually enhanced at 670nm along with the increase of the concentration of H2O2, and the fluorescence emission intensity at 670nm and the concentration of H2O2 have a good linear relationship, so that a system which has large Stokes shift (220nm), can detect H2O2 and is excellent in optical performance is formed, and the system has relatively good sensitivity and selectivity on the detection of H2O2. # imgabs0 # 本发明公开了具有大斯托克斯位移的过氧化氢近红外荧光探针FBMH及其制备方法与应用。FBMH结构式如式I所示。FBMH本身几乎没有荧光。当FBMH与H2O2共存时，体系在670nm处出现一个荧光发射峰。随着H2O2浓度增加，体系在670nm处荧光逐渐增强，670nm处荧光发射强度与H2O2浓度具有良好的线性关系，形成
