Abstract
The present invention relates to a metal complex having a structure of chemical formula (I). The metal complex is applied to an organic light-emitting device which emits deep red or near-infrared light, and shows a lower driving voltage and higher luminous efficiency, and has greatly prolonged service life. Therefore, the metal complex has the potential of being applied in the field of organic light-emitting devices. Also provided is an organic light-emitting device, including a cathode, an anode, and an organic layer. The organic layer is one or more of a hole injection layer, a hole transport layer, a light-emitting layer, a hole blocking layer, an electron transport layer, and an electron injection layer; and at least one layer in the organic layer contains the compound of structural formula (I).
