ANTI-BLUE LIGHT COMPOUND, PREPARATION METHOD AND APPLICATION THEREOF

Disclosed is a blue light absorbing compound, its preparation method and use. The compound has high stability and is suitable for high temperature processing conditions as well as outdoor application. A method of covalently bonding a blue light absorbing compound with an ultraviolet light absorbing compound for increasing its stability is also provided. The compound is capable of absorbing or blocking ultraviolet light (UVA, UVB) and blue light to protect eyes. But long-wavelength blue light can be absorbed diminishingly, so that the transmitted light has a particularly good visual experience.

Novel polycyclic compound

The invention provides a novel polycyclic compound as well as a synthesis method and application thereof. The compound of the present invention includes a plurality of carbocyclic and/or heterocyclicstructures having visible or fluorescent light emitting groups and covalently bonded to at least one ultraviolet and/or visible (blue) light absorbing group to provide stability. The compound providedby the invention can be used as a light conversion agent, a dye, a pigment, a fluorescent agent and an ultraviolet light or blue light absorbent, and can be applied to optical films, agricultural films, optical discs (disks), optical lenses, goggles, skin care, cosmetics, illumination, coatings, adhesives, light stabilizers, panels and other products.
