Paragraph 0041-0042, (2017/04/03)
The invention belongs to the technical field of organic photoelectric materials and discloses an aromatic amino derivative substituted phenol or alkoxybenzene small-molecular hole-transport material which is represented as the structure general formula (I) or (II), and preparation and applications thereof. The preparation method includes the steps of: dissolving tribromophenol or tribromo alkoxybenzene with an aromatic amino boric acid derivative in an organic solvent, adding an alkali water solution, adding a palladium catalyst in the presence of nitrogen, performing a reaction at 30-110 DEG C for 0.5-48 h, and separating and purifying a reaction product to obtain the compound. Through a Suzuki reaction one-step method, an electron donor, aromatic amino derivative, is introduced to an ortho-position and a para-position of the phenol or the alkoxybenzene, so that the product has excellent hole-transport and electron barrier performances, and especially, aromatic amino derivative tri-substituted phenol is easy to dope with lead metal cationic ion to achieve excellent hole-transport performance without an extra doping agent, so that the material can be used in the field of perovskite solar cells.
