Abstract
Novel polycyclic compounds, synthesis methods and applications thereof are provided. The compound comprise a plurality of carbocyclic and/or heterocyclic structures having at least one group that emits visible light or fluorescence and at least one ultraviolet and/or visible (blue) light absorbing group covalently bonded to provide stability. The compounds can be used as a light conversion agent, dye, pigment, fluorescence agent, ultraviolet light or blue light absorber, and is applied to optical film, agricultural film, optical disk (disc), optical lens, goggles, skin care, makeup, lighting, coatings, adhesives, light stabilizers, or panels.
