Abstract:To find an array of suitable materials for phosphorescent organic light‐emitting diodes (OLEDs), in this paper, we design six blue‐green phosphorescent Ir (III) complexes that have low‐efficiency roll‐off properties. Density functional theory and time‐dependent density functional theory were used to study the properties of (2‐[4‐phenoxyphenyl]pyridine [oppy])2Ir(acetylacetonate [acac]), (oppy)2Ir(picolinate [pic]), (oppy)2Ir(tetraphenylimido‐diphosphinate [tpip]), (5‐fluoro‐2‐(4‐phenoxyphenyl)pyridine [F‐oppy]… Show more
