AI Technical Summary
Existing organic optoelectronic devices have shortcomings in terms of efficiency and life, making it difficult to achieve high efficiency and long life performance.
Using a composition comprising the first compound, the second compound and the third compound, the first compound has high electron transport characteristics, the second compound has high hole transport characteristics, and the third compound has broad HOMO-LUMO band gap and low hole mobility. Through the synergistic action of these compounds, the structure and performance of the luminescent layer are optimized.
The high efficiency and long life of the organic optoelectronic device are achieved. By finely adjusting the moving characteristics of electrons and holes, exciton quenching and hole traps are reduced, and the overall performance of the device is improved.
