Abstract

The invention discloses a compound, an application thereof and an organic electroluminescence diode device containing the same. The compound has a structure of a formula (I) and is used as an electrontransmission material in the organic electroluminescence device; the organic electroluminescence device comprises a substrate, a first electrode, a second electrode and at least one organic layer inserted between the first electrode and the second electrode, wherein the organic layer contains any one or a combination of at least two of the compounds. The compound has higher electron injection capability and electron migration capability, and when the compound is applied to the organic electroluminescence device, the device can have higher luminous efficiency, lower starting voltage, longer service life and high stability.

Description

technical field [0001] The invention relates to the technical field of organic electroluminescence, in particular to a compound and its application, and an organic electroluminescence device containing it. Background technique [0002] Organic electroluminescent (OLED: Organic Light Emission Diodes) devices are a type of device with a sandwich-like structure, including positive and negative electrode film layers and an organic functional material layer sandwiched between the electrode film layers. Apply voltage to the electrodes of the OLED device, positive charges are injected from the positive electrode, and negative charges are injected from the negative electrode. Under the action of the electric field, the positive and negative charges migrate in the organic layer and recombine to emit light. Due to the advantages of high brightness, fast response, wide viewing angle, simple process, and flexibility, OLED devices have attracted much attention in the field of new display...
