Abstract

The invention discloses an organic iridium metal complex. The structural general formula of the organic iridium metal complex is shown in the specification, and in the formula, R1 represents a mono-,di-, tri-, tetra-, five or six substituent group; R2 represents a mono-, di-, tri-, tetra-substituent; R1, R2, R3, R4 and R5 each independently represent hydrogen, deuterium, halogen, cyano, sulfinyl,sulfonyl, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaryl group. The invention provides an organic iridium metal complex with a novel structure, and the organic iridium metal complex is an organic metal compound prepared by selecting a specific heterocyclic ligand for combination and adjusting the physical properties of the compound. After being used for an organic light-emitting device, the organic iridium metal complex improves the light-emitting efficiency and prolongs the service life of the device.

Description

technical field [0001] The invention relates to the field of organic photoelectric materials, in particular to an organic iridium metal complex and its preparation method and application. Background technique [0002] Organic electroluminescent technology is the latest generation of display technology. Light-emitting devices made of organic light-emitting materials have the advantages of lightness, thinness, and flexibility in appearance, especially flexible devices, which are incomparable advantages of other light-emitting materials. . Over the past decade, the technology has made some progress on the road to commercialization. For example, organic light-emitting diodes (OLEDs) have been used in advanced displays for smartphones, televisions and digital cameras. Organic electroluminescent materials are the core and foundation of electroluminescent devices. The development of new materials is the driving force for the continuous progress of electroluminescent technology. Th...
