The invention discloses a benzoperyleneimide derivative and its preparation method and application. The structural formula of the benzoperyleneimide derivative is ,or , is prepared from 3,4,9,10-perylenetetracarboxylic anhydride as the initial raw material through multi-step reactions. The benzoperyleneimide derivative has a strong blue light absorption ability, and the molar absorptivity at the maximum absorption wavelength reaches more than 50000mol -1 cm -1 , and there is no absorption in other visible light regions of 500-800nm. The spectral properties of this derivative can be prepared into blue light absorbing materials for daily anti-high-energy short-wave radiation fields, such as anti-blue light coatings on mobile phone screens, anti-blue light coatings on eyeglass lenses, and anti-blue light coloring on paper. |
