| titleOfInvention | Electroluminescent device with iridium complex |
| abstract | An iridium complex Ir(III)L 1L2L3 for emitting light with a central iridium ion Ir(III), with a ligand L3 as dionate from the group comprising pentane-2,4-dionate (acac), 2,2,6,6-tetramethyl-3,5-heptandionate (thd), 7,7-dimethyl-1,1,1,2,2,3,3-heptyfluoro-4,6-octandionate (fod), 4,4,4-trifluorol-(2-thienyl)butane-1,3-dionate (ttfa), 1,3-diphenylpropane-1,3-dionate (dbm), 4,4,4-trifluoro-1-(2-naphthyl)butane-1,3-dionate (tfnb) or 4,4,4-trifluoro-1-(1-naphthyl)butane-1,3-dionate and with two rigid aromatic ligands L1 and L2 with one nitrogen and one carbon atom, sharing in the ligand bond, preferably dibenzo[f,h]chinoline, benzo[h]chinoline or 5,6-dihydro-benzo[h]chinoline, characterized in that the iridium complex Ir(III)L1L2L3 is a first isomer (71), in which the nitrogen atom of the ligand L1 sharing in the ligand bonding and the nitrogen atom of the ligand L2 sharing in the ligand bonding are juxtaposed relative to the central iridium ion. The invention further relates to a method for the separation of the first isomer (71,81) of the iridium complexes ( 7,8 ) and an electroluminescent device with an electroluminescent layer ( 4 ) comprising light-emitting materials, wherein the component of the first isomer (71,81) in the total quantity of the light-emitting materials is greater than 90%, preferably greater than 95%. |
