The present invention relates to compounds of the formula (1) which are suitable for use in electronic devices, in particular organic electroluminescent devices, and to organic electroluminescent devices which comprise these compounds.
Disclosed in the present invention are a fused ring compound and applications thereof in organic electronic components, particularly in organic electroluminescent diodes. Also disclosed in the present invention are an organic electronic component comprising the fused ring compound, and applications thereof in organic electroluminescent diodes and in display and lighting technologies. Further disclosed in the present invention are a formulation comprising the fused ring compound, and applications thereof in the preparation of organic electronic components. By optimizing the component structure, good component performance can be achieved, and especially a high-performance OLED component can be implemented, which provide good material and preparation technology choices for full-color display and lighting applications.
The present disclosure relates to an aromatic amine derivative represented by general formula (I).
The aromatic amine derivative has fluorescence emission at a short light emission wavelength, and the light-emission spectrum of the aromatic amine derivative has a narrow half-peak width, and accordingly, the material has deep-blue fluorescence emission and has a very-high light emission efficiency. An organic electroluminescent component prepared by using the aromatic amine derivative has deep-blue color coordinates, a high light emission efficiency and a long life-span.
