Organic electroluminescent material and application thereof in optoelectronic devices

Abstract

The invention provides an organic electroluminescent material and application thereof in optoelectronic devices. The organic electroluminescent material according to the invention having the structure of Formula (I), the compound of which contains a unit formed by imidazole and indenopyrrole, with its spiro structure molecule that is beneficial to inhibit the stacking between molecules. The compound has better thermal stability and will be applied to organic electroluminescent devices with characteristics such as luminous efficiency and color purity, has the potential to be applied to organic electroluminescent devices. The invention further provides an optoelectronic device including a cathode, an anode, and an organic layer. The organic layer is one or more of a hole injection layer, a hole transport layer, a light-emitting layer, a hole-blocking layer, an electron injection layer, and an electron transport layer. At least one layer of the organic layer contains the compound having Formula (I).
