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).

Metal complex and application thereof

The present invention relates to a platinum metal complex and an application thereof in an organic light-emitting device. The platinum metal complex is a compound having a structure of chemical formula (I). An organic light-emitting device to which the compound is applied has a relatively low driving voltage, a relatively high luminous efficiency and improved service life to a certain extent; therefore, the 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).

Platinum metal complex and use thereof in organic electroluminescent device

The invention relates to a platinum (ii) tetradentate onno complex luminescent material, preparation method and application thereof in organic light emitting diode. A platinum (II) tetradentate pyridine diphenol ONNO complex light-emitting material having the chemical structure of Formula (I) can be used for manufacturing organic light-emitting diodes emitting pure red light. The light-emitting material of the invention, because the end of the left side thereof is connected to benzofuran, has more red shift than the emission spectrum of the bipyridyl phenol ONNO-Pt(II) complex without a benzofuran group, and the anti-aggregation performance of the platinum(II) complex is effectively increased, as a B group is introduced on the phenolic ring on the right side thereof, so the self-quenching rate constant is low, and the color purity emitting deep red light and better luminous efficiency can be maintained in a certain range of doping concentration, which is more suitable for industrial preparation systems.
