  • Publication number: 20200270280
    Abstract: The present disclosure provides an organic compound, an electron transport material, and an application thereof. The organic compound has a structure as shown in Formula I. Design of molecular structure and substituents enables it to undergo tridentate coordination or tetradentate coordination with metal, and more stably and firmly combination with metal, so that it has stronger stability and longer working life when used as an electron transport material, which effectively solves a problem of rising drift voltage. The organic compound has greater rigid distortion, which can suppress an increase of intermolecular attraction and prevent it from forming a planar structure to cause excessive intermolecular attraction. The organic compound is used as an electron transport material, and can be applied to an electron transport layer and/or an electron injection layer of an OLED device, which can effectively improve luminous efficiency and working life of the device, and reduce turn-on voltage.
