Triarylamine

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.

Preparation and structure
Triarylamines can be produced by arylation of diarylamides with aryl iodides:
 * Ar2NLi + Ar'I  ->  Ar2Ar'N  +  LiI

Buchwald-Hartwig coupling methods have also been applied.

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