AI Technical Summary

Technical Problem

Existing organic electroluminescent materials have poor performance, resulting in high device driving voltage, low current efficiency, and short lifespan, which limits the industrial application of OLEDs.

Method used

An organic electroluminescent compound is provided, which is used as a functional layer of OLED by using a compound with a specific structure. By regulating molecular energy levels and carrier transport, concentration quenching and exciton annihilation are suppressed, and the formation of stable amorphous thin films is promoted.

Benefits of technology

This reduces the device's drive voltage, improves current efficiency, and extends its lifespan.
