Abstract

The invention belongs to the field of a luminescent material, and concretely relates to an organic photoelectric material and a preparation method and an application thereof. The organic photoelectricmaterial of the present invention has a structural formula of the formula I shown in the specification. The organic photoelectric material of the present invention is a compound formed by different decorative groups grafted on phenylethylene, can better adjust the transmission performance of electron or hole of phenylethylene derivatives, and the materials can be used as light-emitting layers inorganic electroluminescent devices, and can be used as both the light-emitting layer and a carrier transmission layer, and the electroluminescent device having good photoelectric performance, simple structure, and low cost can be obtained.

Description

technical field [0001] The invention belongs to the field of luminescent materials, and in particular relates to an organic photoelectric material and its preparation method and application. Background technique [0002] Organic electroluminescent materials have many advantages: large optical path range, easy to obtain blue light, high brightness, high efficiency, low driving voltage, low energy consumption, simple manufacturing process and low cost. Therefore, there is a huge demand for organic electroluminescent materials in thin film transistors, solar cells, nonlinear light-emitting materials, polymer light-emitting diodes, etc., showing a wide range of application prospects, so it has become a very popular research topic in the scientific and industrial circles. one. Although many countries in the world have invested heavily in the research and development of organic flat panel display devices, their industrialization process is far below people's expectations, mainly ...
