Embodiment approach

[0123] The OLED includes a first electrode and a second electrode, and a layer of organic material between the electrodes. The organic material can in turn be divided into regions. For example, the organic material layer may include a hole transport region, a light emitting layer, and an electron transport region.

[0124] In particular embodiments, a substrate may be used either below the first electrode or above the second electrode. The substrates are all glass or polymer materials with excellent mechanical strength, thermal stability, water resistance and transparency. In addition, a thin-film transistor (TFT) may be provided on a substrate for a display.

[0125] The first electrode may be formed by sputtering or depositing a material used as the first electrode on the substrate. When the first electrode is used as the anode, oxide transparent conductive materials such as indium tin oxide (ITO), indium zinc oxide (IZO), tin dioxide (SnO2), zinc oxide (ZnO) and any comb...

Abstract

The present invention relates to a novel organic compound, which has a structure represented by the following formula (1): wherein one of A and B represents a formula Y1, the other represents a formula Y2, and the specific structure is represented by the following formula: in Y2, Y2a is fused with a mother nucleus at a c, d or e position. When the compound provided by the invention is used as a light-emitting host material in an OLED device, excellent device performance and stability are shown. The invention also discloses an organic light-emitting device adopting the compound with the generalformula.

Description

technical field [0001] The invention relates to an organic compound, which can be used as a host material for a light-emitting layer of an organic electroluminescent device, and also relates to the application of the compound in an organic electroluminescent device. 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 success in the field of information display. OLED can provide...
