Electron transport material and application thereof

The present disclosure relates to an electron transport material and an application thereof. According to the electron transport material, a structure of a molecular is designed and selected to be constructed by a group having a high carrier mobility, such that the molecule has a higher carrier mobility. In addition, a core group of the molecule is a structure based on mesitylene triazine. The molecular rigidity of the structure is strong, and the intermolecular stacking can be effectively inhibited, such that the material has a lower refractive index, and the surface plasma polariton loss of an organic light-emitting device can be effectively suppressed. The forward light-emitting efficiency of the light-emitting device can be improved by more than 14% by applying the electron transport material to the device.
