Abstract:
1. A compound of the formula (1) where the following applies to the symbols and indices used: X is C═O, C(R) Y is C; W is on each occurrence, identically or differently, CR or N, with the proviso that not more than three groups W in a ring stand for N, and with the further proviso that W=C if a group E is bonded to this group W; Z is, identically or differently on each occurrence, CR or N; or two adjacent groups Z stand for a group of the formula (2) E is, identically or differently on each occurrence, a single bond, C(R) Ar is a group of one of the following formulae (7), (8), (9), (10): A is R if m =n =0, and is an aryl or heteroaryl group having 5 to 30 aromatic ring atoms, which may in each case be substituted by R, or a group —CR═CR—, —CR═N— or —N═N— if an index m or n =1 and the other index m or n =0, or is an aryl or heteroaryl group having 5 to 30 aromatic ring atoms, which may in each case be substituted by R, if the indices m =n =1; R is selected on each occurrence, identically or differently, from H, D, F, Cl, Br, I, CN, NO R R Ar m is 0; n is 0 or 1, where, for n=0, a group R instead of the group E is bonded to A; p is 1; wherein said heteroaryl groups and heteroaromatic ring systems contain at least one heteroatom selected from the group consisting of N, O, and S.
