Abstract: Compounds of General formula I and General Formula II have substituents which may result in a non-planar configuration. This molecular geometry may be effective in reducing excimer formation. The compounds described herein may therefore have improved blue color purity. The compounds have utility in light emitting diodes and light emitting devices.

Abstract: Organic light emitting devices (OLEDs) are described, the OLEDs comprising an anode; a cathode; and an organic region, disposed between the anode and the cathode, comprising a first complex and a second complex; wherein when a voltage is applied across the anode and cathode at room temperature, the OLED emits a luminescent radiation that comprises one or more luminescent radiation components resulting from the formation of at least one exciplex; wherein the exciplex is formed by at least one of the following aggregate types: 1) at least one aggregate within the first complex, and at least one aggregate within the second complex; 2) at least one aggregate between the first and the second complex; and 3) both 1 and 2.
