AI Technical Summary
Existing organic electroluminescent materials suffer from poor stability and low transmission efficiency, leading to reduced device luminescence efficiency and shortened lifespan, and are unable to balance hole-electron transport.
Organic compounds with benzo[a]fluorene, furan, and thiophene fused oxyphenanthrene as the core structure are improved by introducing electron-deficient heteroaryl groups as electron injection and transport groups, thereby enhancing the polarity and conjugated electron cloud density of the material and improving the directional alignment of the material.
It improves the luminous efficiency of organic electroluminescent devices, extends device lifetime, enhances carrier transport efficiency, reduces crystallinity, and improves film formation properties.
