This invention relates to luminescent lanthanide(III) chelates based on β-diketones comprising an azacycloalkane backbone and biomolecule conjugates and solid supports comprising these chelates. In contrast to lanthanide chelates based on monomeric β-diketones as well as lanthanide(III) chelates based on acyclic azaalkanes including several β-diketone subunits, the molecules of the present technology are luminescent even in the absence of additional chelators such as phosphine oxides.

The invention relates to an enhancement solution for an assay technology using lanthanide ions or their chelates as labels and dissociative fluorescence enhancement as a tool for detection, wherein said enhancement solution comprises a ß-diketone of formula (I) wherein R1 is an aryl, optionally mono- or multi-substituted, and R2 is a straight or branched alkyl chain with 2 to 9 carbon atoms substituted with four or more fluorine atoms. The invention further relates to a bioaffinity assay using lanthanide ions or their chelates as labels and dissociative fluorescence enhancement as a tool for detection comprising the use of said enhancement solution.
