AI Technical Summary

Technical Problem

In existing organic electroluminescent devices, exciton diffusion at the interface between the luminescent layer and the electron transport layer leads to reduced luminous efficiency and shortened lifetime. It is necessary to improve the stability and migration characteristics of electrons to improve device efficiency and reduce driving voltage.

Method used

Novel compounds represented by chemical formula 1 are used as electron transport layer or electron transport auxiliary layer materials to suppress exciton diffusion and improve electron mobility, forming a multilayer structure to optimize device performance.

Benefits of technology

Organic electroluminescent devices with higher luminous performance, lower driving voltage, and longer lifespan have been developed, improving the performance and lifespan of full-color display panels.
