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

Abstract

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.
