Provided are a compound, a material for an organic electroluminescent device and an application thereof. The compound has a structure which is formed by substituting at any substitutable position of a structure represented by Formula I with at least one cyano group. The compound has a relatively high refractive index in the region of visible light (400-750 nm) and a reduced extinction coefficient K. When used in the organic electroluminescent device especially as a material for a capping layer, the compound can effectively improve the light extraction efficiency of an organic optoelectronic device, improve external quantum efficiency (EQE), implement display at various angles, and can effectively alleviate a color cast.

naphthalene via chiral phosphoric acid catalysis. This strategy enables efficient construction of atropisomeric indole-naphthalenes and indole-anilines with excellent stereocontrol. Density functional theory (DFT) calculations provide further insights into the origins of enantioselectivity and the reaction mechanisms. The successful application in the synthesis of NOBINs (2-amino-2′-hydroxy-1,1′-binaphthyl)
