High‐efficiency red‐emitting polymer light‐emitting diodes utilizing [PhqIr]‐doped non‐conjugated and conjugated polymers (see Figure) in the presence of electron transport molecules are reported. An external quantum efficiency of 12 % photon/electron and a luminous efficiency of 5.2 cd/A with saturated red emission at 624 nm are demonstrated.
