Microwave synthesis of novel Ir(III) complexes and their application to an electroluminescence device

A microwave synthetic method has been developed for novel electroluminescent Ir(III)-polypyridine complexes. The novel Ir(III)-polypyridine complexes give intensively multi-colored luminescence whose emission peaks are occurred ranging from 450 to 630 nm. The chemical properties and electroluminescence character of these Ir(III) complexes are studied. These Ir complexes exhibit red electrophosphorescence and they might be promising red emitting materials for EL devices.
