QSРR ANALYSIS OF THE LUMINESCENT CHA,RACTERISTICS OF Еu(III) AND Тb(III) COMPLEXES WITH 2-OXO-4-HYDROXYQUINOLINE-3-CARBOXYLIC ACID AMIDES

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,QSРR models, which were constructed on the simplex and circular descriptors weighed by informational potentials of the atoms. The received consensus models are ade,quate, offers satisfactory predicting ability (R2test=0,915,0,986) and indicate priority influence of electros,tatic factor and Van der Waals relationships on the quantum yield of luminescence and the lifetime of the excited state of lanthanide ions.

Keywords: 2D, QSРR models, luminescence, europium, terbium, hydroxyquinoline,3,carboxylic acids
