Abstract
The present invention relates to a formulation comprising at least one solvent and at least two functional compounds of the general formula (I) where A is a functional structural element, B is a solubility-promoting structural element and k is an integer in the range from 1 to 20, the molecular weight of the functional compound is at least 550 g/mol and the solubility-promoting structural element B conforms to the general formula (L-I) where Ar1, Ar2 is each, independently of one another, an aryl or heteroaryl group, which may be substituted by one or more radicals R of any desired type, X is in each case, independently of one another, N or CR2, preferably CH, R1, R2 is each, independently of one another, hydrogen, 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 or is a silyl group or a substituted keto group having 1 to 40 C atoms, an alkoxycarbonyl group having 2 to 40 C atoms, an aryloxycarbonyl group having 7 to 40 C atoms, a cyano group (CN), a carbamoyl group (C(═O)NH2), a haloformyl group (C(═O)—X, in which X represents a halogen atom), a formyl group (C(═O)—H), an isoc…
