Abstract
The fluorescence of praseodymium(III) complex containing 2,2'-bipyridine, [Pr(bpy)2Cl3·OH2] has been investigated in details. Also, the biological activity of [Pr(bpy)2Cl3·OH2] has been evaluated by examining its ability to bind to DNA with UV-vis, fluorescence as well as viscosity measurement. The fluorescence of [Pr(bpy)2Cl3·OH2] is strongly quenched through static mechanism in the presence of DNA. DNA intrinsic binding constant, Kb the binding site number, n the Stern-Volmer quenching constant, KSV and the thermodynamic parameters have been determined by fluorescence spectroscopy. For characterization of bonding mode, the effect of various experimental parameters were investigated on the interaction of [Pr(bpy)2Cl3·OH2] with DNA. Copyright ÂEntities:
