Abstract

The invention provides a compound, an electroluminescent device and application of the device. The compound has a structure as shown in a formula I, is a novel triarylamine compound which is connected with an aza-aromatic ring and contains a naphthalene or aza-naphthalene structural unit, and can be used as a charge transport material or a host material in the electroluminescent device. According to the compound, the structure is improved through the design of a molecular structure and substituent groups, the driving voltage of an electroluminescent device can be reduced, the luminous efficiency is improved, the service life of the device is remarkably prolonged, and the electroluminescent device can fully meet the requirements of commercial application.

Description

technical field [0001] The invention belongs to the technical field of organic electroluminescence materials, and in particular relates to a compound, an electroluminescence device and applications thereof. 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. OLED is becoming more and more popular for its unique superior performance such as wide color gamut, almost infinitely high contrast ratio, extremely high response speed, bendability, and energy saving. [0003] In 1987, Tang and Van Slyke of Eastman Kodak reported...
