Claim:
A perfluoroalkyl-containing complexes with a nitrogen-containing linker structure of formula I in which Q is a direct bond, R means a polar radical that is a carbon chain with 1-30 C atoms that is bonded via —CO—, —NR 7 — or a direct bond to linker L, which can be straight or branched, saturated or unsaturated, and which optionally is interrupted by 1-10 oxygen atoms, 1-5 —NHCO groups, 1-5 —CONH groups, 1-2 sulfur atoms, 1-5 —NH groups or 1-2 phenylene groups, which optionally can be substituted by 1-2 —OH groups, 1-2 —NH 2 groups, 1-2 —COOH groups, or 1-2 —SO 3 H groups, and which optionally is substituted by 1-10 —OH groups, 1-5 —COOH groups, 1-2 SO 3 H groups, 1-5 —NH 2 groups, or 1-5 C 1 -C 4 -alkoxy groups, R 7 means H or C 1 -C 4 -alkyl, R f is a perfluorinated, straight-chain or branched carbon chain with the formula —C n F 2n E, in which E represents a terminal fluorine, chlorine, bromine, iodine or hydrogen atom, and n stands for the numbers 4-30, K stands for a metal complex of formula II, in which R 1 means a hydrogen atom or a metal ion equivalent of atomic numbers 21-29, 31-33, 37-39, 42-44, 49 or 57-83, provided that at least two R 1 stand for metal ion equivalents, R 2 and R 3 , independently of one another, represent hydrogen, C 1 -C 7 -alkyl, benzyl, phenyl, —CH 2 OH or —CH 2 OCH 3, and U stands for a C 1 —C 12 -alkylene group that optionally is interrupted by one or more oxygen atoms, 1 to 3 —NHCO groups, or 1 to 3 —CONH groups and/or is substituted by 1 to 3 —(CH 2 ) 0-5 COOH groups, wherein ω stands for the binding site to —CO—, and free acid groups, optionally present in radical K, can optionally be present as salts of organic and/or inorganic bases or amino acids or amino acid amides, and L represents a radical IXc) wherein q′is 1,2,3 or 4, wherein α means the binding site of L to complex K, β is the binding site of L to radical Q, and γ represents the binding site of L to radical X, and X stands for a group of formula (VI) ρ-y—(CH 2 ) s -(G) t -(CH 2 ) s′ -ζ (X) wherein Y means a direct bond, wherein R 6 stands for —H or a straight or branched, saturated or unsaturated C 1 -C 15 carbon chain, which can be interrupted by 1-4 O atoms, 1-3 —NHCO groups, 1-3 —CONH groups, 1-2 —SO 2 groups, 1-2 sulfur atoms, 1-3 —NH groups or 1-2 phenylene groups, which optionally can be substituted by 1-2 OH groups, 1-2 NH 2 groups, 1-2 —COOH groups or 1-2 —SO 3 H groups, and which optionally is substituted by 1-10 OH groups, 1-5 —COOH groups, 1-2 —SO 3 H groups, 1-5 NH 2 groups, or 1-5 C 1 -C 4 -alkoxy groups, and G means either —O— or —SO 2 —, s and s′, independently of one another, mean 1 or 2, t means 0, and ρ represents the binding site of X to L and ξ represents the binding site of X to R f .
