Tris(2-phenylbenzo[b]thiophenato-N,C³′)iridium(III) (Ir(btpy)₃)(CAT: M440035) is a phosphorescent iridium complex developed as an efficient orange-to-red emitter for organic light-emitting diodes (OLEDs). Incorporating benzo[b]thiophene-based ligands, Ir(btpy)₃ combines strong spin–orbit coupling, excellent photoluminescence efficiency, and high thermal stability. Its ability to harvest both singlet and triplet excitons enables near-unity internal quantum efficiency, while its rigid aromatic framework ensures stable thin-film morphology and extended device lifetimes. Ir(btpy)₃ delivers saturated emission with high brightness and color purity, making it a valuable material for OLED displays and solid-state lighting. With robustness and versatility, it remains an important iridium emitter for next-generation optoelectronics.
