Claim:
A compound of formula (1) wherein Y is on each occurrence, identically or differently, B, N, P, P═O, PF 2 , C═O, O, S, S═O, or SO 2 ; Ar is on each occurrence, identically or differently, an aromatic or heteroaromatic ring system having 5 to 40 aromatic ring atoms, optionally substituted by one or more radicals R 1 ; X is on each occurrence, identically or differently, a group selected from C(R 1 ) 2 and C═O or a combination of these groups; Z is C if a group X is bonded to the group Z, or is CR if no group X is bonded to the group Z; W is CH; R is on each occurrence, identically or differently, H, D, or CH 3 ; E is on each occurrence, identically or differently, a single bond, N(R 1 ), O, S, C(R 1 ) 2 , C(R 1 ) 2 -C(R 1 ) 2 , Si(R 1 ) 2 , or B(R 1 ); R 1 is on each occurrence, identically or differently, H, D, F, Cl, Br, I, CN, NO 2 , B(OR 2 ) 2 , Si(R 2 ) 3 , a straight-chain alkyl, alkoxy, or thioalkoxy group having 1 to 40 C atoms or a straight-chain alkenyl or alkynyl group having 2 to 40 C atoms or a branched or cyclic alkyl, alkenyl, alkynyl, alkoxy, or thioalkoxy group having 3 to 40 C atoms, each of which is optionally substituted by one or more radicals R 2 , and 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 , —O—, —S—, —COO— or —CONR 2 —, and wherein one or more H atoms are optionally replaced by F, Cl, Br, I, CN or NO 2 , or an aromatic or heteroaromatic ring system having 5 to 40 aromatic ring atoms, optionally substituted by one or more non-aromatic radicals R 1 , or an aryloxy or heteroaryloxy group having 5 to 40 aromatic ring atoms, optionally substituted by one or more non-aromatic radicals R 1 ; and wherein two or more substituents R 1 optionally define a mono- or polycyclic ring system with one another; R 2 is on each occurrence, identically or differently, H or an aliphatic or aromatic hydrocarbon radical having 1 to 20 C atoms; m and n are 0 or 1, with the proviso that m+n=1; q is on each occurrence 1 if the corresponding central atom of the group Y is an element from main group 3 or 5 and is on each occurrence 0 if the corresponding central atom of the group Y is an element from main group 4 or 6; s is 1; t is on each occurrence, identically or differently, 0 or 1, wherein when t is 0, radicals R 1 are bonded instead of the group E and q is 0; v is 0 or 1, where when v is 0, hydrogen or a group R may be bonded instead of the group Y; and wherein at least one radical R represents a substituent other than H or D.
