Abstract

The invention belongs to the technical field of organic photoelectric materials, and discloses a tetraphenylethylene-containing organic semiconductor material and a preparation method thereof, and application of the material in organic photoelectric devices. The tetraphenylethylene-containing organic semiconductor material is disclosed as Formula I or II, wherein R1, R2, R3, R4 and R5 can be identical or different aromatic ring derivative groups. Different modification groups can be connected to the tetraphenylethylene to regulate the electronic or hole transmission performance of the tetraphenylethylene derivatives, so that the organic semiconductor material not only can be used as a luminescent layer, but also can be used as a luminescent layer and current carrier transmission layer, thereby obtaining the electroluminescent devices with favorable photoelectric properties, simple structure and low cost; and the organic semiconductor material has wide application prospects in the fields of organic electroluminescence, organic field-effect transistors, organic solar cells and other organic electronics.

Description

technical field

[0001] The invention belongs to the technical field of organic photoelectric materials, in particular to an organic semiconductor material containing tetraphenylethylene, a preparation method thereof and an application in organic photoelectric devices. Background technique

[0002] With the rise and vigorous development of the organic electronics industry, organic optoelectronic materials have become the focus of scientific research at home and abroad because of their broad application prospects in the fields of organic electroluminescent diodes, organic solar cells, organic field effect transistors, organic lasers, and chemical sensors. And one of the hotspots of product development. However, most conventional luminescent materials do not emit light in the solid state due to intermolecular interactions leading to non-radiative energy conversion or the formation of species unfavorable for fluorescence emission.

[0003] The molecular structure of tetraphenyl...
