First Examples of Alkenyl Pyridines as Organic Ligands for Phosphorescent Iridium Complexes

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

Summary:The first successful synthesis of iridium complexes {(PEP)2Ir(acac), (NEP)2Ir(acac), (PETP)2Ir(acac), (MPEP)2Ir(acac), and (PP)2Ir(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.
