AI Technical Summary
While existing organic electroluminescent devices have advantages in terms of light-emitting properties due to their organic layer materials, their low glass transition temperature and poor thermal stability result in unsatisfactory lifetimes.
Novel compounds represented by chemical formula 1 are used as electron transport layer or electron transport auxiliary layer materials by combining benzene rings substituted with triazine derivatives and introducing specific substituents, such as phenyl groups, onto the benzene rings to improve electron mobility and thermal stability.
It realizes an organic electroluminescent element with low driving voltage, high efficiency and long life, and improves electron transport capability, electrochemical stability and thermal stability, which is suitable for full-color display panels.
