  • METAL-ASSISTED DELAYED FLUORESCENT EMITTERS EMPLOYING PYRIDO-PYRROLO-ACRIDINE AND ANALOGUES
    Publication number: 20230322833
    Abstract: Metal-assisted delayed fluorescent (MADF) emitters including cyclic tetradentate platinum (II) and palladium (II) complexes employing 8H-pyrido[3?,2?:4,5]-pyrrolo[3,2,1-de]acridine and its analogues. These complexes provide improved color purity and enhanced operational stability and are suitable for luminescent labels, emitters for organic light emitting diodes (OLEDs), and lighting applications.
