A π‐conjugated polymer‐iridium complex containing the ligand in the main chain was synthesized by the Suzuki coupling method, and was applied to organic light‐emitting devices (OLEDs) as the emitter material. The polymer‐iridium complex showed red photoluminescence and electroluminescence with the maximum external quantum efficiency of ca. 3% by using 4,4′‐ N , N ′‐dicarbazole‐biphenyl and 2‐(4‐biphenylyl)‐5‐(4‐ tert ‐butyl‐phenyl)‐1,3,4‐oxadiazole blended into the polymer emitter layer.
