Luminescent 4-trifluoromethyl 1-2-quinolones with long wave UV absorption and the use thereof

A substituted 4-triflouromethylcarbostyril compound according to formula 1 above, wherein the compound shows an absorption maximum between 350 and 420 nm and a luminescence maximum between 430 and 900 nm, the defined groups X and Y having the meaning NH, N-alkyl and oxygen in any combination,

• R1 and R2 either means a methylene bound over X and Y together, 1,2-ethylene, 1,3-propylene or in any combination hydrogen, alkyl from C1 to C11 and if necessary alkyl substituted with functionalised groups, which alkyl is suitable for complexing metal ions or serves for binding the molecule to suitable groups of a target molecule or solid carrier material, and
• the residues R3 and R4 means hydrogen or that either one of them is hydrogen and the other residue is suitable for complexing metal ions or is suitable for binding the molecule to suitable groups of a target molecule or solid carrier material, or that this other residue if necessary carries a functionalised side chain that at the same time is suitable for binding the molecule to functional groups of a target molecule or solid carrier material and for complexing trivalent metal ions of the group of the lanthanides, or that both residues R3 and R4 each mean a functionalised side chain, one for binding the molecule to suitable groups of a target molecule or solid carrier material and a side chain for complexing of trivalent metal ions from the group of the lanthanides.
