Direct nitration method of electron-enriched aromatic hydrocarbons

The invention discloses a direct nitration method of electron-enriched aromatic hydrocarbons, and belongs to the field of organic synthesis. The direct nitration method is a novel green free radical nitration method; aromatic hydrocarbons are taken as raw materials, acetonitrile, dichloromethane, chloroform, or acetone is taken as a reaction solvent, at room temperature conditions, the raw materials and green nitration reagent tert-butyl nitrite (TBN) are subjected to free radical nitration so as to obtain nitro-aromatic compounds. According to the direct nitration method, no metal is adoptedin reaction, tert-butyl nitrite is directly adopted in nitration reaction. Electron-donating groups such as OMe are introduced, the electron density of aromatic compounds is increased, the nitration reaction possibility is increased. The using amount of tert-butyl nitrite is reduced; only a product and tert-butyl alcohol are generated, environment pollution is reduced. The direct nitration methodis promising in application prospect in the field of nitro-aromatic compound synthesis, green nitration is realized, and a novel idea is provided for large-scale industrialized nitro-aromatic compoundproduction.

Benzodioxane group containing hole-transport material, preparation method therefor and application of hole-transport material

The invention discloses a benzodioxane group containing hole-transport material, a preparation method therefor and an application of the hole-transport material and belongs to the technical field of perovskite solar cells. The hole-transport material has a molecular structure represented by a formula shown in the description. The invention also discloses the preparation method for the hole-transport material and the application of the hole-transport material in perovskite solar cell devices. Simultaneously, the invention also discloses a perovskite solar cell device. According to the hole-transport material disclosed by the invention, different alkyl chains are introduced to a parent nucleus or side chain so as to improve solubility; by introducing diarylamine with a spatial three-dimensional form or a carbazole group, the crystallization of the material can be avoided, and then, the stability of the material is improved; and meanwhile, due to a spatial three-dimensional structure, the solubility of the material can be improved, and then, the film forming property is improved.
