This invention belongs to the fields of functional fluorescent dyes and biomedical technology, specifically relating to a near-infrared squaric acid cyanine dye with ultra-high fluorescence brightness, its preparation method, and its application. A water-soluble charged 1,8-naphthoylimide derivative is obtained through an imino substitution reaction of 1,8-naphthoylimide, which is then coupled with squaric acid to obtain a near-infrared squaric acid cyanine dye with ultra-high fluorescence brightness.
