The invention discloses a 1,8-naphthalimide compound bonded with spiro-pyran, a preparation method and applications thereof. The 1,8-naphthalimide compound is prepared by modifying the N position of naphthalimide by photochromic spiro-pyran. The invention also discloses a specific preparation method of the compound. Before the compound is irradiated by light, the compound has a light yellow color. When the compound is activated by light, the compound gives off green fluorescence. When the compound is irradiated by light with a wavelength of 365 nm, the color of the compound is converted from yellow to orange red and the compound gives off brick red fluorescence. The compound is a light controllable photochromic and dual-component light controlled fluorescence molecular switch, is a bifunctional material, which has excellent performances of phototropy and photoluminescence, and has a wide application prospect.
