NOVELTY - Iridium complexes (I) are new.    USE - (I) are useful in organic electronic device (claimed) including devices that convert electrical energy into radiation (e.g. a light-emitting diode, light emitting diode display, diode laser, or lighting panel), devices that detect signals through electronic processes (e.g. photodetectors photoconductive cells, photoresistors, photoswitches, phototransistors, phototubes, infrared detectors, or biosensors), devices that convert radiation into electrical energy (e.g. a photovoltaic device or solar cell), devices that include one or more electronic components that include one or more organic semiconductor layers (e.g. a transistor or diode), coating materials for memory storage devices, antistatic films, biosensors, electrochromic devices, solid electrolyte capacitors, energy storage devices such as a rechargeable battery, and electromagnetic shielding applications. (I) are useful as oxygen sensitive indicators, as phosphorescent indicators in bioassays, and as catalysts.    DETAILED DESCRIPTION - Iridium complexes of formula (I) are new.    R1 = indole, indoline, carbazole, tetrahydrocarbazole, phenanthroline, phenazine, phenanthridine, quinoxaline, pyrrole, azole, oxazole or pyridine (each of which is attached via N) or CH(Ar1)2;    R2, R3 = H, CnF2n+1, CnF2n+1SO2, COOR4 or CN;    R4 = H, alkyl, or aryl;    Ar1 = aryl;    L1a = polydentate ligand that is not a phenylpyridine, phenylpyrimidine, or phenylquinoline;    L2a = monodentate ligand, and is not a phenylpyridine, phenylpyrimidine, or phenylquinoline;    m = 1-3;    n = 1-20;    y = 0-2; and    z = 0-4.    With the proviso that the compound is charge neutral and the iridium is hexacoordinate.
