ABSTRACT:
The present invention is directed to organic light emitting devices comprising a heterostructure for producing electroluminescence having a hole transporting layer with a glass structure. The hole transporting layer comprises a compound having a symmetric molecular structure. The end groups of the symmetric molecule are hole transporting amine moieties having an unsaturated linkage between two arenes.
