三-(2-苯基吡啶)合铱[红外（聚吡咯）3]是一种重金属复合物。[红外（聚吡咯）3]是合成磷光材料最常用的前体分子，磷光材料随后被用于有机发光二极管(OLED)。它提供接近统一的绿色发射和高磷光量子产率。 OLED triplet emitter (green). Tris-(2-phenylpyridine) iridium [Ir(ppy)3] is a heavy metal complex. [Ir(ppy)3] is the most frequently used precursor molecule for the synthesis of electro-phosphorescent materials, which are then used in organic light emitting diodes (OLEDs). It provides green-color emission and high phosphorescence quantum yield close to unity.
