Abstract

The invention relates to thiophene derivative and application thereof. The chemical structure of the thiophene derivative is represented by the formula (1), wherein, X is substituted or unsubstituted C6-C20 aryl or C1-C20 alkyl; R1 and R2 are H, and C1-C10 straight chain, branched chain or cyclic alkyl independently, or R1, R2 and carbon atoms in the formula (1) forms a first heterocycle together; R3 and R4 are H, and C1-C10 straight chain, branched chain or cyclic alkyl independently, or R3, R4 and carbon atoms in the formula (3) forms a second heterocycle together; b is integer from 1 to 10; and when R1, R2, R3 and R4 are all H, the X is not H (in the formula 2). The invention also provides a conductive material including the thiophene derivative. The invention also provides a organic luminescent material including the thiophene derivative.

Description

technical field [0001] The present invention relates to a thiophene derivative, in particular to a thiophene derivative suitable for organic light-emitting materials or conductive materials. Background technique [0002] At present, there are many applications of light-emitting diodes in daily life. Most of the traffic lights at intersections and large display screens involve the use of inorganic light-emitting diodes; as for light-emitting diodes based on organic materials, on the one hand, they can be further expanded to make displays On the other hand, it has the advantages of self-illumination, high response speed, power saving, no viewing angle limit, light weight, thin thickness, high brightness, full-color display, and animation image display, which is suitable for various portable communication products. Japan's Mitsubishi General Research Institute predicts that organic light-emitting diodes will become the mainstream of the next generation of small and medium-sized...
