COMPLEXING BENZO-CONTAINING HETEROCYCLIC COMPOUNDS, CONTAINING β-DICARBONYL SUBSTITUTE WITH FLUORINATED RADICALS Russian patent published in 2009 - IPC C07D333/56 C07D209/12 C07D307/80 C07D279/20 C07D215/14 C07C49/80 C07F5/00 

FIELD: chemistry.

SUBSTANCE: invention relates to synthesis of new complexing analytical reagents which are suitable for doping nanoparticles and for use in luminescence-spectral analysis, biochip technology, as well as extractants of ions of heavy and rare-earth metals. Description is given of complexing benzo-containing heterocyclic compounds, which contain a β-dicarbonyl substitute with fluorinated radicals of formula: HetAr-C(O)CH2C(O)CF₃, where HetAr= ,

which form luminescent complexes with Eu³⁺ ions. Proposed compounds are on the same level as compounds with closely resembling structure with regards to duration of luminescence and bonding efficiency, although they are easily accessible with respect technology of production and have high water solubility >10^-4 mol/l, which enables their use in making conceptually new biochips with time, spatial and spectral signal selection.

EFFECT: high output of desired product.
