摘要:
The invention is directed to bipyridine-based compounds and organic light emitting diodes (OLED) including organic layers comprising the bipyridine-based compound. OLEDs including organic layers comprising the bipyridine-based compounds have low driving voltages, high current densities, high efficiencies and long lifetimes.
