The Claisen condensation of diesters of fluorinated dicarboxylic acids with 2-acetyl-naphthalene affords the corresponding naphthyl-containing tetraketones and diketo esters. The luminescence-spectral properties and stability constants of complexes of these compounds with Eu3+ ions were estimated. The characteristics of the complexes are comparable with those of fluorinated β-diketones containing chromophoric substituents, which are widely used in luminescence analysis. The synthesized naphthyl-containing diketo esters are efficiently conjugated with proteins and can be used for detection of biospecific interactions.
