Highly Efficient and Stable Green Phosphorescent Light‐Emitting Diodes Based on Solution‐Processable Ir(III) Complexes with Electron‐Transporting Ancillary Ligands

Abstract

Scheme 1. Synthetic routes of Ir(III) complexes (Ir(CF 3 BNO) 2 -pop and Ir(BNO) 2 -pop).

Tetradentate Pt[O^N^C^N] complexes with peripheral diarylamino substituents for high-performance and stable green organic light-emitting diodes with LT95 of 17 140 h at 1000 cd m−2

“…Among the numerous phosphorescent materials developed so far, iridium complexes have been extensively studied and successfully used as high-performance green and red emitters in commercial organic light-emitting diodes (OLEDs). 1–3 Phosphorescent iridium( iii ) complexes exhibit significantly superior photophysical properties, 4–6 which are difficult to match with other metal phosphors reported in the public domain. However, the growing demand for OLEDs requires other suitable emitter options to reduce the continued reliance on iridium, one of the rarest metals in the earth's crust.…”
