Patent ID: 8343637

Claim:
A compound of the formula (1) wherein Ar is on each occurrence an aromatic or heteroaromatic ring system having 5 to 60 aromatic ring atoms, which is optionally substituted by one or more radicals R 1 ; Ar 1 is on each occurrence, identically or differently, an aromatic or heteroaromatic ring system having 5 to 60 aromatic ring atoms, which is optionally substituted by one or more radicals R; R is on each occurrence, identically or differently, Cl, Br, I, N(Ar 2 ) 2 , CN, NO 2 , Si(R 2 ) 3 , B(OR 2 ) 2 , C(═O)Ar 2 , P(═O)(Ar 2 ) 2 , S(═O)Ar 2 , S(═O) 2 Ar 2 , —CR 2 ═CR 2 (Ar 2 ), OSO 2 R 2 , a straight-chain alkyl, alkoxy or thioalkoxy group having 1 to 40 C atoms or a branched or cyclic alkyl, alkoxy or thioalkoxy group having 3 to 40 C atoms, each of which is optionally substituted by one or more radicals R 2 , where one or more non-adjacent CH 2 groups is 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 where one or more H atoms is optionally replaced by F, Cl, Br, I, CN or NO 2 , or an aromatic or heteroaromatic ring system having 5 to 60 aromatic ring atoms, which in each case is optionally substituted by one or more radicals R 2 , or an aryloxy or heteroaryloxy group having 5 to 60 aromatic ring atoms, which is optionally substituted by one or more radicals R 2 , or a combination of these systems; two or more substituents R here optionally form a mono- or polycyclic aliphatic or aromatic ring system with one another; R 1 is on each occurrence, identically or differently, R, a group Ar 1 or F; Ar 2 is on each occurrence, identically or differently, an aromatic or heteroaromatic ring system having 5 to 60 aromatic ring atoms, which is optionally substituted by one or more radicals R 2 ; R 2 is on each occurrence, identically or differently, H or an aliphatic, aromatic or heteroaromatic hydrocarbon radical having 1 to 20 C atoms; two or more substituents R 2 here optionally form a mono- or polycyclic aliphatic or aromatic ring system with one another; n is on each occurrence, identically or differently, 0, 1, 2 or 3; p is on each occurrence, identically or differently, 0, 1, 2, 3 or 4; and q is 1, 2, 3, 4 or 5.
