Influence of the ligands structure 2-oxo-4-hydroxyquinoline-3-carboxylic acid amide derivatives on luminescent characteristics of their complexes with lanthanide ions

Relationships of the luminescent characteristics of europium (III) and terbium (III)complexes of hydroxyquinoline carboxylic acid amide derivatives with their structure has been established by means of 2D-QSÐR models, which were constructed on the simplex descriptors weighed by informational potentials of the atoms. The received models are adequate (R2=0,998�0,972, Q2=0,957� 0,850), offers satisfactory predicting ability (R2 test=0,926�0,712) and indicate priority influence of electronic polarization of the ligands and their topology on the quantum yield of luminescence and the lifetime of the excited state of lanthanide ions.

Keywords: 2D-QSPR models luminescence europium terbium hydroxyquinoline carboxylic acids
