Two novel pyrenederivatives 1-3,5-diphenylphenyl-6-[2-(3,5-diphenylphenyl)phenyl]pyrene (PyPP) and 1-3,5-diphenylphenyl-6-[2-(9-phenyl-9H-carbazol-3-yl)phenyl]pyrene (PyPC) were successfully synthesized and characterized. Both these compounds exhibit unsymmetrical and highly twisted structures, and show efficient deep-blue emissions and high thermal stabilities. The non-doped electroluminescence devices
