The first successful synthesis of iridium complexes {(PEP) 2 Ir(acac), (NEP) 2 Ir(acac), (PETP) 2 Ir(acac), (MPEP) 2 Ir(acac), and (PP) 2 Ir(acac)} (see Figure) using an olefin‐tethered pyridine ring is described. The electroluminescent devices prepared using these iridium complexes as dopant emitters showed very high brightness and efficiencies.
