High performance hybrid white and multi-colour electroluminescence from a new host material for a heteroleptic naphthyridinolate platinum complex dopant

By employing a new heteroteptic platinum complex FPtmND as the single dopant in a conventional CBP or new 4P-NPD host, high efficiency greenish-yellow or orange-red phosphorescent OLEDs, and high colour rendering index hybrid white OLEDs have been achieved with relatively simple device configuration.
