ABSTRACT:
The use of conjugated compounds which contain two or more pyrimidine rings as part of the conjugated system as electroluminescence materials. The conjugated compounds containing pyrimidine rings have a high thermal stability and a high photostability. They are partially soluble in acids, which also makes possible processing from solution, as well as by vapor deposition.
