Abstract

The invention relates to a near-infrared fluorine-boron dipyrrole fluorochrome and a preparation method thereof. According to the method, halogenated isoindole imine and a boric acid reagent Suzuki are coupled, and then the near-infrared fluorine-boron dipyrrole fluorochrome is synthesized through acid catalysis condensation, wherein the emission wavelengths of the fluorochrome in various solvents are greater than 669nm, and the emission spectrum of the fluorochrome and derivatives thereof can reach 748nm. The fluorochrome has relatively high fluorescence quantum yield (0.67-1) and excellent optical physicochemical properties, such as light stability, and has a good application prospect in fields like laser dye and bioanalysis.

Description

technical field

[0001] The invention relates to the technical fields of functional fluorescent dyes, organic chemicals and fine chemicals, in particular to a near-infrared fluoroboron dipyrrole fluorescent dye and a preparation method thereof. Background technique

[0002] Fluoroboron dipyrrole molecules are a class of fluorescent dye molecules with excellent photophysical and chemical properties that have only been developed in the past two decades. Chemical batteries, light-harvesting antenna systems and other fields have very good application prospects, and are widely used, especially the long-wave near-infrared fluoroboron dipyrrole molecule. Therefore, the synthesis of near-infrared fluoroborate dipyrrole fluorescent dyes has received greater attention. The approach of the near-infrared BODIPY fluorescent dye of synthesizing long-wave absorption emission usually has following several at present: 1) introduce aryl, vinyl, styryl, arylethynyl etc. [Rurack, K.; Kollmannsb...
