Ir(btpy)3, efficient red PhOLED

High-purity (>99.0%) and available online for priority dispatch


Tris(2-(benzo[b]thiophen-2-yl)pyridineiridium, known as Ir(btpy)3, is an efficient red phosphorescent emitter (PHOLED). It is commonly used in organic light-emitting diodes and polymer solar cells as a dopant, and in barometric pressure probes due to its sensitivity to oxygen [2].

Wang et al. demonstrated that a higher Ir(btpy)3 doping concentration is beneficial to photon harvesting in the active layer, but the interpenetrating network of P3HT:PCBM can be damaged through high-temperature annealing treatment [3].
