Abstract

Abstract Starting from N, N-diarylsubstituted thioureas 20 and thioacetamides 21 a series of heterocyclic analogous of N, N′-perarylated phenylene-1, 4-diamines and benzidines was obtained. These compounds represent, as studied by DSC measurements, a new class of hole transporting materials with high thermal stability and high tendency to form stable amorphous states. Moreover, some of the new compounds are, as measured by cyclic ...
