Near infrared BODIPY (Boron Dipyrromethene Compounds) hydroxyl radical probes and synthesis method and usage thereof

The invention discloses a kind of near infrared boron dipyrromethene compounds (BODIPY) based on duplex thiophene pyrrole groups. The near infrared boron dipyrromethene compounds have the following structure: FORMULA, wherein the group at meso site is changed to obtain a series of hydroxyl radical probes. The BODIPY hydroxyl radical probes based on 3,5-(diphenyl phosphate styryl) are synthesized for the first time in the invention, the 3,5 site groups of the BODIPY are introduced into the group, so that the absorption spectrum red shift of the probe reaches 630nm, the emission peak reaches 650nm and is located within the range (650-900nm) of a biological window, and meanwhile, the fluorescence quantum efficiency of the probe is high. Moreover, the kind of probes can be used for efficiently and quickly detecting hydroxyl radicals and can be successfully applied in biological imaging. Therefore, the probes have a brilliant application prospect of detecting the hydroxyl radicals in biological systems.
