Triarylamine Explained

In chemistry, a triarylamine has the formula NAr₃ where Ar is any of several aryl groups. The parent member is triphenylamine. Triarylamines are of interest as components of molecular electronics as well as some dyes.^[1]

Preparation and structure

Triarylamines can be produced by arylation of diarylamides with aryl iodides:

Buchwald-Hartwig coupling methods have also been applied.^[2]

Many hundreds of triarylamines have been prepared. In some cases, their radical cationic derivatives have been characterized by X-ray crystallography.
