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.
