  Novel organic compounds containing an imidazole core and electron donor and acceptor fragments are provided. By selection of the disclosed donor and acceptor groups, compounds exhibiting small singlet-triplet gaps are obtained. These compounds are useful in OLED devices as host materials or as delayed fluorescent emitters.

  A composition formed of a mixture of two compounds having similar thermal evaporation properties that are pre-mixed into an evaporation source that can be used to co-evaporate the two compounds into an emission layer in OLEDs via vacuum thermal evaporation process is disclosed. The first and second compounds can have an evaporation temperature T 1 and T 2 , respectively, of 150 to 350° C., and the absolute value of T 1 −T 2 can be less than 20° C. The first compound can have a concentration C 1 in the mixture and a concentration C 2 in a film formed by evaporating the mixture in a vacuum deposition tool at a constant pressure between 1×10 −6 Torr to 1×10 −9 Torr, at a 2 Å/sec deposition rate on a surface positioned at a predefined distance away from the mixture being evaporated, where the absolute value of (C 1 −C 2 )/C 1 is less than 5%.
