Abstract

The invention relates to a heterocyclic organic photoelectric material, and a preparation method and an application thereof. The material is a compound represented by formula I shown in the description. The material of the invention is a heterocyclic aromatic hydrocarbon derivative has excellent chemical stability and electron mobility; the material is synthesized in one step, so the conversion rate is high; and the material has the advantages of excellent electron transport property and hole mobility, good thermal stability, high efficiency, low driving voltage and difficulty in crystallization, so the material is applied to an electroluminescent device to achieve low driving voltage, high brightness, good thermal stability, long half-life cycle, low cost and 2-3 times longer life.

Description

technical field [0001] The invention belongs to the technical field of electroluminescence, and in particular relates to a heterocyclic organic photoelectric material and its preparation method and application. Background technique [0002] Organic electroluminescent devices (OLEDs) have the advantages of high efficiency, high brightness, low driving voltage, fast response, and large-area photoelectric display. Therefore, they have great application prospects in the fields of display and high-efficiency lighting. [0003] OLED is an injection light-emitting device, and its basic structure is a sandwich structure formed by sandwiching an organic thin film layer between two electrodes. The organic thin film layer consists of a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer and an electron injection layer. layer composition. The hole transport layer (HTL) is responsible for adjusting the injection rate and amount of holes, and...
