AI Technical Summary

Technical Problem

Existing boron-nitrogen materials suffer from poor solubility and film-forming properties due to their rigid structure, which easily leads to efficiency roll-off and limits their application in printed OLED technology.

Method used

Design an organoboron-nitrogen compound with a specific structure, optimize its molecular structure to improve its solubility in organic solvents, and form a light-emitting layer through spin coating or inkjet printing. Combine this with a specific device layer structure layout to improve carrier recombination efficiency.

Benefits of technology

This invention achieves high luminous efficiency, excellent color purity, and long lifespan in organic electroluminescent devices, suitable for printed OLED technology, simplifying the fabrication process and reducing efficiency roll-off.
