摘要： A compound, a material for an organic electroluminescent device and an application thereof are disclosed herein. The compound has a structure represented by Formula (1). The compound has a relatively high refractive index and can effectively improve the light extraction efficiency. The external quantum efficiency of the compound makes it suitable for use as a capping layer when used in an organic electroluminescent device. The compound has a relatively high refractive index in the region of visible light (400-750 nm), which is advantageous for improving the light-emitting efficiency. The compound has a relatively large extinction coefficient in the ultraviolet region (less than 400 nm), which is advantageous for absorbing harmful light and protecting eyesight. Meanwhile, a deuterium atom may be introduced into the compound to significantly improve the device lifetime.
