【Abstract】 Dyes are widely used in people’s production and life, greatly improving people’s lives. Croconaine dye is an emerging near-infrared-absorbing dye, which is the focus of research and application in recent years due to its good photothermal stability, high fluorescence quantum yield, and large molar absorption coefficient. It has important application value in biomedicine, optical therapy,fluorescence imaging and other fields. In this paper, the structural characteristics and physicochemical properties of near-infrared-absorbing croconaine dyes were summarized, the research progress on the syntheses and application of croconaine dyes in the past decade was introduced, and the application prospects of the dye are envisioned, providing reference for the further development and utilization of croconaine dyes.更多还原
