Patent ID: 8115379

Claim:
An electronic component comprising an emitter, wherein the emitter comprises a metal complex containing one or more 2-(3-thienyl)-pyridine ligands, wherein the metal complex has a structure according to general formula 1 or 2: wherein M is a heavy metal; X, Y, and LL are ligands, wherein the ligands are independently charged or uncharged, wherein the ligands produce essentially no emission, wherein X and Y, independently of one another, comprise a single negative charge or neutral monodentate ligand, and are selected from the group consisting of F − , Cl − , Br − , I − , CN − , NCO − , SCN − , R 4 S − , R 4 O − , R 4 C═C − , R 4 COO − , NO 3 − , amine, phosphane, arsane, nitrile, isonitrile, CO, carbene, ethers, and thio-ethers, wherein R 4 is an organic radical with 1 to 15 carbon atoms, and wherein each LL comprises a chelating ligand and/or a cyclometallating ligand, and is selected from the group consisting of β-diketonate, β-diketoiminate, [(pyrazolyl) 2 H] − , [(pyrazolyl) 2 BR 5 2 ] − , [pyrazolyl 3 BH] − , [pyrazolyl 4 B] − , (triazolyl) 2 BH 2 − , (triazolyl) 3 BH − , (triazolyl) 4 B − , (Ph 2 PCH 2 ) 2 BR 5 2 − , R 5 COO − , NO 3 − , diamine, diphosphane, diarsane, dinitrile, diisonitrile, dialkyl ethers, and dialkyl (thio)ethers, wherein R 5 is an organic radical with 1 to 15 carbon atoms; R 1 and R 2 , independently of one another, may be present one or more times on each respective cycle, and are independently selected from F, Cl, Br, I, NO 2 , CN, a straight-chain alkyl, branched alkyl, cyclic alkyl, or alkoxy group, wherein the straight-chain alkyl, branched alkyl, cyclic alkyl, or alkoxy group comprises 1 to 20 carbon atoms wherein one or more non-adjacent CH 2 groups in the straight-chain alkyl, branched alkyl, cyclic alkyl, or alkoxy group may be replaced by —O—, —SiR 3 2 —, —S—, —NR 3 —, or —CONR 3 — and wherein one or more H atoms in the straight-chain alkyl, branched alkyl, cyclic alkyl, or alkoxy group may be replaced by F, an aryl group, or heteroaryl group, wherein the aryl group or heteroaryl group comprises 4 to 14 C atoms, which may be substituted with one or more non-aromatic radicals R 1 or R 2 ; wherein two or more of substituents R 1 and/or R 2 , both on the same ring and/or on the two different rings, may together form a further monocyclic or polycyclic ring system; R 3 is identical or different each time it occurs and is selected from H, an aliphatic hydrocarbon radical, or aromatic hydrocarbon radical, wherein the aliphatic hydrocarbon or aromatic hydrocarbon radical comprises 1 to 20 carbon atoms; wherein n is an integer from 1-3; wherein m and 1, independently of one another, are integers from 0-4, wherein 2n+m+1=4 or 6, or p=0−2 and 2n+2p=4 or 6.
