Abstract
Described are novel platinum (II) containing organometallic materials. These materials show green to orange emissions with high emission quantum efficiencies. Using the materials as emitting materials; pure green emitting organic light-emitting diodes can be fabricated. Since the novel platinum (II) containing organometallic materials are soluble in common solvents, solution process methods such as spin coating and printing can be used for device fabrication.
