The invention discloses an
iridium-containing
metal compound and an organic light-emitting device thereof, and relates to the technical field of an organic photoelectric material. The
iridium-containing
metal compound has a structure shown as a formula (I) and structurally comprises a first ligand and an auxiliary ligand, wherein an
electron-rich dinitrogen coordination structure in the auxiliaryligand structure is favorable for stabilizing the center trivalent
metal cations; meanwhile, the electronic cloud distribution on the metal
iridium can also be influenced; great influence can be generated on the photoelectric property of the whole compound molecules; in addition, a four-membered ring formed by the ligands of the dinitrogen coordination structure and metal has higher rigidity; theunnecessary vibration
energy loss can be favorably reduced; the efficient luminous performance is realized; by regulating the
substituent groups, the compound has higher stability and better chemicalproperties. When the iridium compounds are prepared into devices, particularly when the iridium compounds are used as
doping materials, the device shows the advantages of low driving
voltage and highluminous efficiency and is superior to the existing common use
OLED (Organic
Light Emitting Diode) device.
