| Abstract: | 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. Published in Russian in Izvestiya Akademii Nauk. Seriya Khimicheskaya, No. 2, pp. 269—273, February, 2006. |
