US 2017/0365798 A1 · FLUORINATED AROMATIC SMALL MOLECULES AS FUNCTIONAL ADDITIVES FOR DISPERSION OF CONDUCTIVE POLYMERS

Abstract

The present invention relates to a compound having a general formula selected from the group consisting of formula 1a and 1b, wherein K represents an aromatic or heteroaromatic group in which at least one hydrogen atom may be substituted by a functional groups selected from the group consisting of a sulfonic acid group, a sulfuric acid group, an ammonium group and an aliphatic group; X is selected from the group consisting of a C—C-bond, O, S, SO2 and NR′, wherein R′ represents a hydrogen or an aliphatic or aromatic group; A represents a fluorinated or perfluorinated aromatic group; n represents an integer in the range from 2 to 6; m represents an integer in the range from 1 to 3. The present invention also relates to a composition comprising this compound, to a process for the preparation of a conductive layer using this composition, to a conductive layer comprising the compound according to the present invention, to electronic components comprising this conductive layer and to the use of the compound according to the present invention as an additive in a hole-injection layer of an OLED or in an organic solar cell.
