Organic compound, electroluminescent device containing organic compound and application thereof

Abstract

The invention provides an organic compound, an electroluminescent device containing the organic compound and application thereof. The organic compound has a structure shown in a formula 1, a dicarbazole group in the organic compound is connected to a triazine group, and dicarbazole is connected with the triazine group at a second position or a fourth position. When the organic compound is applied to an electroluminescent device as a luminescent layer main body material and / or a hole blocking layer material, the electroluminescent device using the organic compound has relatively low driving voltage and relatively high external quantum efficiency.

Description

technical field [0001] The invention belongs to the technical field of organic electroluminescence materials, and relates to an organic compound, an electroluminescence device containing the same and its application. Background technique [0002] Organic electronic devices include but are not limited to the following categories: organic light-emitting diodes (OLEDs), organic field-effect transistors (O-FETs), organic light-emitting transistors (OLETs), organic photovoltaic devices (OPVs), dye-sensitized solar cells (DSSCs) , organic optical detectors, organic photoreceptors, organic field-effect devices (OFQDs), light-emitting electrochemical cells (LECs), organic laser diodes, and organic plasmonic light-emitting devices. [0003] In 1987, Tang and Van Slyke of Eastman Kodak reported a double-layer organic electroluminescent device that included an arylamine hole-transport layer and a tris-8-hydroxyquinoline-aluminum layer as the electron-transport layer and emitted light ...
