Claim:
An organic electronic device comprising a compound of formula (1) wherein Ar 1 is, identically or differently on each occurrence, a fused aryl or heteroaryl group having at least 14 aromatic ring atoms optionally substituted by one or more R; X is, identically or differently on each occurrence, a group of formula (2) or (3) wherein the dashed bond is a link from Ar 2 or Q to Ar 1 ; Y is, identically or differently on each occurrence, X; an Ar 3 group; or an N(Ar 3 ) 2 group, wherein the two Ar 3 radicals are optionally bonded to one another by a single bond or via an O, S, N(R), or C(R) 2 group; Ar 2 is, identically or differently on each occurrence, an aryl or heteroaryl group optionally substituted by one or more R and to which a group Q is bonded, with the proviso that either the group Q or an R other than H is bonded in the ortho-position to the Ar 1 -Ar 2 bond; Ar 3 is, identically or differently on each occurrence, an aromatic or heteroaromatic ring system optionally substituted by one or more R; Q is, identically or differently on each occurrence, a linear, branched, or cyclic alkylene or alkylidene group which forms two bonds to Ar 2 or one bond to Ar 1 and one bond to Ar 2 and thereby defining a further ring system; wherein Q has up to 20 C atoms optionally substituted by R 1 , wherein one or more non-adjacent C atoms are optionally replaced by N—R 1 , O, S, O—CO—O, CO—O, —CR 1 ═CR 1 —, or —C≡C—, and one or more H atoms are optionally replaced by F, Cl, Br, I, or CN, wherein Q is bonded to the ortho-position of Ar 2 , where said ortho-position is relative to the link between Ar 2 and Ar 1 ; R is, identically or differently on each occurrence, H, F, Cl, Br, I, CN, a straight-chain alkyl or alkoxy chain having up to 40 C atoms, or a branched or cyclic alkyl or alkoxy group having 3 to 40 C atoms, wherein said straight-chain alkyl or alkoxy chain or said branched or cyclic alkyl or alkoxy group are optionally substituted by R 1 , wherein one or more non-adjacent C atoms are optionally replaced by N—R 1 , O, S, O—CO—O, CO—O, —CR 1 ═CR 1 —, or —C≡C—, and wherein one or more H atoms are optionally replaced by F, Cl, Br, I, CN, or an aromatic or heteroaromatic ring system having 5 to 40 aromatic ring atoms optionally substituted by one or more R 1 , or a combination of two, three or four of these systems; and wherein two or more R here optionally define a further mono- or polycyclic, aliphatic, or aromatic ring system with one another; R 1 is, identically or differently on each occurrence, H or a hydrocarbon radical having up to 20 C atoms, wherein said hydrocarbon radical is optionally aliphatic or aromatic or a combination of aliphatic and aromatic, and wherein one or more H atoms are optionally replaced by F; m is, on each occurrence, 0 or 1; p is, on each occurrence, 0, 1, or 2; with the proviso that the following compound is excluded as a compound of formula (1):
