Abstract

The present invention provides an organic compound which can be represented by the general formula (1). The present invention also includes an organic electroluminescence element made by using the compound as a hole transport material. The compound of the present invention can bring excellent luminescence characteristics and lifetime characteristics to organic electroluminescent devices.

Description

technical field [0001] The present invention relates to organic compounds and organic electroluminescent devices using the same. Specifically, the present invention describes a class of compounds containing aromatic amine substitutions that can be used as hole transport layer materials in organic electroluminescent devices. Background technique [0002] In recent years, optoelectronic devices based on organic materials have become increasingly popular. The inherent flexibility of organic materials makes them very suitable for manufacturing on flexible substrates. They can design and produce beautiful and cool optoelectronic products according to requirements, and obtain incomparable advantages over inorganic materials. Examples of such organic optoelectronic devices include organic light emitting diodes (OLEDs), organic field effect transistors, organic photovoltaic cells, organic sensors, and the like. Among them, OLED is developing rapidly, and has achieved commercial su...
