Patent ID: 8878165

Claim:
A process comprising providing in an electronic device one or more electrodes containing a metal or metal oxide, and depositing onto the surface of said electrodes a layer comprising a compound of formula I, and depositing onto the surface of said electrodes which is covered by said layer comprising the compound of formula I, or depositing in the area between two or more of said electrodes, an organic semiconductor, wherein X 1 , X 2 , X 3 are independently of each other selected from —N(H)—, —N═, ═N—, —C(R x )═, ═C(R x )— and —S—, wherein at least one of X 1 , X 2 and X 3 is different from —C(R x )═ and ═C(R x )—, R x is on each occurrence identically or differently H, NH 2 , or straight-chain or branched alkyl with 1 to 15 C atoms, in which one or more non-adjacent C atoms are optionally replaced by —O—, —NR 0 —, —CO—, —CO—O—, —O—CO—, —O—CO—O—, —CR 0 ═CR 00 — or —C≡C— and in which one or more H atoms are optionally replaced by F, Cl, Br, I or CN, R 1 and R 2 are independently of each other F, Cl, P-Sp-, or straight-chain or branched alkyl with 1 to 15 C atoms, in which one or more non-adjacent C atoms are optionally replaced by —O—, —NR 0 —, —CO—, —CO—O—, —O—CO—, —O—CO—O—, —CR 0 ═CR 00 — or —C≡C— and in which one or more H atoms are optionally replaced by F, Cl, Br, I or CN, or denote aryl, heteroaryl, aryloxy, heteroaryloxy, arylcarbonyl, heteroarylcarbonyl, arylcarbonyloxy, heteroarylcarbonyloxy, aryloxycarbonyl or heteroaryloxycarbonyl having 2 to 30 C atoms that is unsubstituted or substituted by one or more non-aromatic groups R, or R 1 and R 2 , together with each other and with the 5-membered heterocycle to which they are attached, form an aromatic or heteroaromatic ring that comprises 5 to 7 ring atoms and is unsubstituted or substituted by 1, 2, 3, 4 or 5 groups R, R 0 and R 00 are independently of each other H or optionally substituted carbyl or hydrocarbyl optionally comprising one or more hetero atoms, R is on each occurrence identically or differently H, P-Sp-, halogen, —CN, —NC, —NCO, —NCS, —OCN, —SCN, —C(═O)NR 0 R 00 , —C(═O)X 0 , —C(═O)R 0 , —NH 2 , —NR 0 R 00 , —SR 0 , —SO 3 H, —SO 2 R 0 , —OH, —NO 2 , —CF 3 , —SF 5 , optionally substituted silyl, carbyl or hydrocarbyl with 1 to 40 C atoms that is optionally substituted and optionally comprises one or more hetero atoms, P is a polymerizable or crosslinkable group, Sp is a spacer group or a single bond, and X 0 is halogen.
