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.
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 transport materials for OLEDs.

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

The oxidative coupling of N,N-disubstituted 2-aminothiophenes performed by several heavy-metal free oxidizing agents gives rise to the formation of N,N′-persubstituted 5,5′-diamino-2,2′-bithiophenes which are of interest as hole-transport materials for optoelectronic applications.
