SPECIFIC COMPOUNDS - 99 Compounds (I) are disclosed e.g. tris(9-(3-isoquinolin-1-yl-phenyl)-3,6-diphenyl-9H-carbazole)iridium(III) (Ia), tris(9-(3-isoquinolin-1-yl-phenyl)-3,6-dimethyl-9H-carbazole)iridium(III), tris(3,6-bis-(3,5-dimethyl-phenyl)-9-(3-isoquinolin-1-yl-phenyl)-9H-carbazole)iridium(III), tris(9-(3-isoquinolin-1-yl-phenyl)-3,6-di-naphthalen-1-yl-9H-carbazole)iridium(III) and tris(3,6-bis-(3,5-diphenyl-cyclohexa-1,3-dienyl)-9-(3-isoquinolin-1-yl-phenyl)-9H-carbazole)iridium(III).    EXAMPLE - Tris(1-(3-bromophenyl)-isoquinoline)iridium(III) (7 g), 2-phenyl-9H-carbazole (13.1 g) and tripotassium phosphate (57 g) were suspended in p-xylene (850 ml). Then palladium(II) acetate (45 mg) and 1 M tri-tert-butylphosphine (2.7 ml) solution were added to this suspension. Then the reaction mixture was heated for 42 hours under reflux. After cooling, the reaction mixture was worked up to obtain tris(9-(3-isoquinolin-1-yl-phenyl)-2-phenyl-9H-carbazole)iridium(III).
