The present invention relates to a formula, comprising at least one solvent, and at least one functional composition of the general formula (I), wherein A is a functional structural element, B is a solvent-providing structural element, and k is an integer in the range of 1 to 20. The molecular weight of the functional composition is at least 550 g/mol, and the solvent-providing structural element B corresponds to the general formula ((L-I). Ar1, Ar2 JeWeUs, independently of each other, signify an aryl or heteroaryl group, which can be substituted with one or several discretionary residues R. Each X is, independently of one another, N or CR2, preferably CH. R1, R2, independently of one another, is hydrogen, a linear alkyl, alkoxy, or thioalkoxy group with 1 to 40 C atoms, or a branched or cyclic alkyl, alkoxy, or thioalkoxy group with 3 to 40 C atoms, or a silyl group, or a substituted keto group with 1 to 40 C atoms, an alkoxycarbonyl group with 2 to 40 C atoms, an aryloxycarbonyl group with 7 to 40 C atoms, a cyano group (—CN), a carbamoyl group (—C(═O)NH2), a haloformyl group (—C(═O)—X, wherein X signifies a halogen atom), a formyl group (—C(═O)—H), an isocyano group, an isocyanate group, a thiocyanate group or a thioisocyanate group, a hydroxy group, a nitro group, a CF3 group, C1, Br, F, a cross-linkable group, or a substituted or non-substituted aromatic or heteroaromatic ring system with 5 to 60 ring atoms, or an aryloxy or heteroaryloxy group with 5 to 60 ring atoms, or a combination of these systems, wherein one or several of groups R1 and/or R2 can form a monocyclic or polycyclic, aliphatic or aromatic ring system with one another and/or with the ring to which group R1 is bound, and I is 0, 1, 2, 3 or 4, wherein the dashed linkage indicates the linkage to the functional structure element A. The present invention further relates to preferred compositions of the formula (I) and electronic devices containing said compositions.
