Abstract:
A method of making ligands for producing novel heteroleptic iridium complexes is provided. The method includes reacting the condensation product of an aryl 1,2-diamine and an aryl aldehyde with manganese dioxide in a solvent. The novel iridium complexes produced using the ligands are useful compounds in OLED devices.
