Abstract

The invention discloses a 1, 4-2[4-(N, N-p-Methyl-phenyl-amino) styryl] naphthol and the preparation method and application, which belongs to the technology field of photoelectric materials. The structural formula of the component refers to the drawing and the preparation process of the component comprises that: 1-chloromethyl naphthalene reacts with paraformaldehyde and hydrochloric acid under the catalysis of the phosphoric acid to prepare 1, 4- dichloromethylnaphthalene and then reacts with triethyl phosphate to prepare the wittig reagent; the produced wittig reagent reacts with 4-(N, N-2 p-Methyl-phenyl-amino) aminotenzaldehyde under the action of alkali to gain the starting material. The component mixes with bisphenol A Pc resin or bisphenol Z Pc resin to prepare the hole-transporting layer thin film of the organic photoconductor of function separated type. The invention has moderate reaction conditions and has high photosensitivity of the organic photoconductor appliance as the hole-transporting material.

Description

technical field [0001] The invention relates to 1,4-bis[4-(N,N-p-methylphenylamino)styryl]naphthalene and its preparation method and application, belonging to the technical field of photoelectric materials. Background technique [0002] Hole transport materials are a class of organic semiconductor materials that can transport holes. Commonly used in organic photoconductor devices (OPC), organic electroluminescent devices (OLED) and organic solar cells and other fields. Commonly used hole transport materials are hydrazone 4-(N,N-di-p-methylphenyl)aminobenzaldehyde-1,1-diphenylhydrazone (CT106) and butadiene 1,4-bis(p-di Ethylaminophenyl)-4-(α-naphthyl)-4-phenyl-1,3-butadiene (CT8), the structure is as follows: [0003] [0004] Although this type of material is easy to synthesize, due to its high polarity, it cannot be used for resins such as bisphenol Z Pc resins that are soluble in non-polar solutions, and it is easy to crystallize and decompose. [0005] Triarylamine...
