High-efficiency organic light-emitting diodes of phosphorescent PtAg₂heterotrinuclear acetylide complexes supported by triphosphine

Abstract

Platinum(<sc>ii</sc>)–silver(<sc>i</sc>) heterometallic cluster complexes are used as a new type of phosphorescent dopant to achieve high-efficiency OLEDs with 67.4 cd A⁻¹peak current efficiency (CE) and 17.4% external quantum efficiency (EQE).
