Organic optoelectronic materials and organic electroluminescent devices including the organic materials

摘要

An organic electroluminescent device comprising an organic optoelectronic material and the organic material, wherein the organic optoelectronic material is represented by Formula I, and R ₁ and R ₂ each independently represent a hydrogen group, a cyano group, an isothiocyanato group, and a phenyl group R ₃ , R ₄ , R ₅ , R ₆ , R ₇ and R ₈ each independently represent a hydrogen atom, a halogen atom, and at least one of N, S, and O having 10 to 50 carbon atoms, And an aromatic heterocyclic group containing an aromatic heterocyclic group. The organic optoelectronic material may be applied to an organic electroluminescent device as a light emitting material to improve the maximum current efficiency of the organic electroluminescent device, reduce the turn-on voltage of the organic electroluminescent device, To extend the spectral coverage of the system.
