AI Technical Summary

Technical Problem

Existing organic electroluminescent materials have low stability and poor matching between HOMO and LUMO energy levels and adjacent energy levels, resulting in an imbalance in carrier mobility. This leads to high driving voltage, low luminous efficiency, and short lifetime in organic electroluminescent devices.

Method used

An organic compound is provided in which a core with a specific structure is connected to an aromatic amine containing a benzoxazole structure and combined with different substituents to improve the stability and hole transport performance of the compound, enhance the matching degree of HOMO and LUMO energy levels, and achieve a balance of carrier mobility.

Benefits of technology

The driving voltage, luminous efficiency, and lifetime of organic electroluminescent devices have been improved. By optimizing the structural design of organic compounds, a balance of carrier mobility has been achieved, thereby enhancing the performance of the devices.
