Title:
ELECTRON TRANSPORT MATERIAL AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/024557
Kind Code:
A1
Abstract:
The present invention relates to an electron transport material and an application thereof. According to the electron transport material, a molecular structure is designed to be constructed by selecting a group having high carrier mobility, so that a molecule has the high carrier mobility; in addition, a core group of the molecule is based on a structure of mesitylene triazine; the molecule of the structure has strong rigidity, so that intermolecular stacking can be effectively inhibited, the material has a low refractive index, and the surface plasmon polariton loss of an organic electroluminescent device can be effectively suppressed. The forward light emitting efficiency of the device can be improved by more than 14% by applying the electron transport material to the electroluminescent device.
