Starting from N,N,C-triarylacetamides and 1-aryl-2-bromoethanones a series of new 3,4-diaryl-substituted 2-diarylaminothiophenes have been prepared and characterized spectroscopically.

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 voltammetry, easily reversibly oxidized indicating the formation of persistent radical ions. Such compounds, which are, in general, completely substituted by aryl groups at their heterocyclic moieties, have been successfully used as hole-transport materials in OLEDs.
Arylated mono- and bifunctional 2-aminothiophenes and 2-aminothiazoles as a new class of hole transport materials
Kanitz, Andreas,Schumann, Joerg,Scheffel, Marcus,Rajoelson, Sambatra,Rogler, Wolfgang,Hartmann, Horst,Rohde, Dirk
, p. 896 - 897 (2007/10/03)
By using the well-known Hantzsch method and starting from some mono- and bifunctional aryl-substituted thioureas, thioacetamides, and bromoketones several new aryl-substituted 2-aminothiazoles and 2-aminothiophenes have been prepared and tested as hole tr
