Claim:
An organic electronic device comprising at least one compound of formulae (2), (3), or (4) wherein the naphthalene group is optionally substituted by one or more radicals R 1 Y is on each occurrence, identically or differently, CR 1 or N; R 1 is, identically or differently on each occurrence, H, F, Cl, Br, I, N(Ar) 2 , C(═O)Ar, P(═O)(Ar) 2 , S(═O)Ar, S(═O) 2 Ar, CR 2 ═CR 2 Ar, CN, NO 2 , Si(R 2 ) 3 , B(OR 2 ) 2 , a straight-chain alkyl, alkoxy or thioalkoxy group having up to 40 C atoms, or a branched or cyclic alkyl, alkoxy or thioalkoxy group having 3 to 40 C atoms, in each case optionally substituted by one or more radicals R 2 , wherein one or more non-adjacent CH 2 groups are optionally replaced by —R 2 C═CR 2 —, —C≡C—, Si(R 2 ) 2 , Ge(R 2 ) 2 , Sn(R 2 ) 2 , C═O, C═S, C═Se, C═NR 2 , P(═O)(R 2 ), SO, SO 2 , —NR 2 —, —O—, —S—, or —CONR 2 — and wherein one or more H atoms is optionally replaced by F, Cl, Br, I, CN, or NO 2 , an aromatic or heteroaromatic ring system having 5 to 40 aromatic ring atoms optionally substituted by one or more radicals R 2 , or an aryloxy or heteroaryloxy group having 5 to 40 aromatic ring atoms optionally substituted by one or more radicals R 2 , or a combination of these systems; and wherein two or more adjacent substituents R 1 optionally define a mono- or polycyclic aliphatic ring system with one another, wherein two groups R 1 on one group C(R 1 ) 2 optionally define a spiro structure, and Ar is on each occurrence an aromatic or heteroaromatic ring system having 5-30 aromatic ring atoms optionally substituted by one or more non-aromatic radicals R 1 ; wherein two radicals Ar on the same nitrogen atom are optionally linked to one another by a single bond or a bridge X; R 2 is, identically or differently on each occurrence, H or an aliphatic, aromatic, or heteroaromatic hydrocarbon radical having up to 20 C atoms; wherein two or more adjacent substituents R 2 optionally define a mono- or polycyclic aliphatic or aromatic ring system with one another; X is, identically or differently on each occurrence, a divalent bridge selected from the group consisting of C(R 1 ) 2 , C═O, C═NR 1 , O, S, S═O, SO 2 , N(R 1 ), P(R 1 ), P(═O)R 1 , C(R 1 ) 2 —C(R 1 ) 2 , C(R 1 ) 2 —C(R 1 ) 2 —C(R 1 ) 2 , C(R 1 ) 2 —O, and C(R 1 ) 2 —O—C(R 1 ) 2 ; and wherein at least one substituent R 1 containing at least one aryl or heteroaryl group is present.
