Description

technical field [0001] The present invention relates to a novel compound and an organic electronic device using the compound, and specifically relates to an electrophotographic photoreceptor, an organic transistor, an organic electroluminescent device, and an organic solar cell. Background technique [0002] Recently, organic electronic materials have received attention. Organic electronics refers to new materials that utilize organic materials as semiconductors instead of conventional inorganic materials. In practical electronic devices using organic materials, the use of active functions caused by current flowing through the materials, so-called active devices, is extremely limited. Among them, the most representative example is an electrophotographic photoreceptor. As examples currently being developed, there are organic electroluminescent elements, organic solar cells, organic transistors, and the like. [0003] As organic electronic materials, there are hole transpor...

AI Technical Summary

Problems solved by technology

[0006] The charge transport material used in the above-mentioned photoreceptor is required to have high carrier mobility, but since charge transport materials with high carrier mobility are almost all hole transport substances, it is practical from the viewpoint of mechanical strength. OPC in OPC is limited to negatively charged laminated photoreceptors with a charge transfer layer on the outermost layer

However, since the OPC of the negative charge treatment uses a negative polarity corona discharge, it has the following problems: it is more unstable than the positive polarity discharge, generates ozone or nitrogen oxides, etc., and easily causes physical and chemical deterioration by adsorption on the surface of the photoreceptor. , but also cause adverse effects on the use environment, etc.

However, the photocarriers generated in the mixed layer cannot be efficiently transferred to the electrodes, so further improvement in efficiency is required for practical use.
