General Description

N,N'-diphenyl-N,N'-bis(2,4-dimethylphenyl)-(1,1'-biphenyl)-4,4'-diamine, also known as 4,4'-bis(N,N'-diphenylamino)biphenyl, is a chemical compound with the molecular formula C36H32N2. It is commonly used as an antioxidant and stabilizer in the production of polymers and plastics, especially in the manufacturing of rubber and rubber products. The compound is known for its ability to inhibit the degradation of materials caused by exposure to heat, light, and air. Additionally, it has been used in the development of organic light-emitting diodes (OLEDs) and organic photovoltaic cells due to its electron-donating and hole-transporting properties. However, it is important to handle this compound with caution as it may be harmful if inhaled, ingested, or comes into contact with the skin.

METHOD FOR PRODUCING TRIARYLAMINE COMPOUND

[Problem] To provide a method for producing a triarylamine compound in which the reaction can be attained under a practical condition, the purification operation after the reaction is simple, the environmental burden is reduced and the production efficiency is high. [Means for Resolution] A method for producing a triarylamine compound through amination of a diarylamine compound and an aryl halide, wherein a catalyst comprising a salt of an imidazolium derivative represented by the following general formula (1) and a palladium compound is used, as combined with a base and a solvent to coexist therein.

Polyaromatic amines. Part 2. Synthesis of 4,4′,4″-tris(N-aryl-N-phenylamino)triphenylamine, N,N-bis[4-(N-aryl-N-phenylamino)-phenyl]tolylamine and N,N,N′,N′-tetraaryl-o-phenylenediamine derivatives

The title compounds were synthesised and characterised as part of a study into new aromatic amines for charge transporting materials. Proton and carbon spectral data for compounds 1-6 were obtained in C6D6 as a consequence of their facile oxidation in CDCl3. Each compound was characterised by cyclic voltammetry. An estimate of the intramolecular charge mobility was deduced from the difference between the first and second oxidation potentials.
