Bipyridine derivatives and their uses for organic light emitting diodes

An organic light-emitting device including a first electrode; a second electrode; and an organic layer disposed between the first electrode and the second electrode, wherein the organic layer comprises an emission layer, and wherein the organic layer comprises a first compound represented by Formula 1 and a second compound having the lowest excited triplet energy level greater than 2.73 electron volts: 

Organic light-emitting device

A chemical compound is provided having a structure that includes at least one donor moiety covalently bonded to at least one acceptor moiety. For example, the compound may include an indolocarbazole moiety covalently bonded to at least one furylpyridine moiety. The compound may exhibit thermally activated delayed fluorescence and an accompanying &#x394;Eof no greater than about 0.25 eV. The compound finds use in OLED display technology.
