The invention discloses near-infrared BODIPY fluorescent dyes, and a synthetic method and application thereof, belonging to the fields of functional fluorescent dyes, organic synthesis and fine chemicals. The fluorescent dyes in the invention comprises two types described in the spectification; the fluorescent dyes as shown in a formula (1) and a formula (2) have the following advantages: excitation and emission spectrum are in a near-infrared region; half-peak breadth is narrow; stokes shift is more than 20; the yield of fluorescent quantum is greater than 0.65; insensitivity to a polar solvent is realized; and excellent chemical stability and optical stability are obtained. The dyes in the invention can be applied in preparation of fluorescent microspheres and have significant reagent application values in the fields of measurement, standard, biological chemistry, medical immunology, analytical chemistry, chemical industry, microelectronic industry and life science. |
