in addition, two or more identical or different radicals RB and RC is optionally linked to one another and form a mono- or polycyclic, aliphatic or aromatic ring system, R1 is on each occurrence, identically or differently, H, D, F, Cl, Br, I, CHO, N(R2)2, C(═O)R2, P(═O)(R2)2, S(═O)R2, S(═O)2R2, CR2═C(R2)2, CN, NO2, Si(R2)3, B(OR2)2, OSO2R2, OH, a straight-chain alkyl, alkoxy or thioalkyl group having 1 to 40 C atoms or a branched or cyclic alkyl, alkoxy or thioalkyl group having 3 to 40 C atoms or an alkenyl or alkynyl group having 2 to 40 C atoms, each of which is optionally substituted by one or more radicals R2, where one or more non-adjacent CH2 groups is optionally replaced by R2C═CR2, C≡C, Si(R2)2, Ge(R2)2, Sn(R2)2, C═O, C═S, C═Se, C═NR2, P(═O)(R2), SO, SO2, NR2, O, S or CONR2 and where one or more H atoms is optionally replaced by D, F, Cl, Br, I, CN or NO2, or a mono- or polycyclic aromatic or heteroaromatic ring system having 5 to 60 aromatic ring atoms, which may in each case be substituted by one or more non-aromatic radicals R2, or an aryloxy or heteroaryloxy group having 5 to 60 aromatic ring atoms, which is optionally substituted by one or more non-aromatic radicals R2, or a combination of these systems, where two or more radicals R1 is optionally linked to one another and may form a mono- or polycyclic, aliphatic or aromatic ring system, R2 is on each occurrence, identically or differently, H, D, F or an aliphatic, aromatic and/or heteroaromatic organic radical having 1 to 20 C atoms, in which, in addition, one or more H atoms is optionally replaced by F; two or more identical or different substituents R2 here may also be linked to one another and form a mono- or polycyclic, aliphatic or aromatic ring system, and the stoichiometric indices s and a are selected, depending on the charge numbers r and p present in the complex in square brackets in formula (I) or in the counterion A, in such a way that overall a charge-neutral compound results, and, for r=0, a=0, (no counterion A is present). |
