Organic iridium metal complex as well as preparation method and application thereof

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. 本发明公开了一种有机铱金属配合物，有机铱金属配合物的结构通式如
