Abstract
Described herein are novel platinum(II) emitters. These materials show high emission quantum efficiency, a low self-quenching constant, and are stable in thermal deposition processes. Organic light-emitting diodes (OLEDs) fabricated from these materials can have pure green emission, high efficiency and low efficiency roll-off. The OLEDs can have a chemical structure of:
