Ionic strength dependence of the enantioselective quenching of tris(2,6-pyridinedicarboxylate)terbium(3-) luminescence by resolved tris(1,10-phenanthroline)ruthenium(2+)

Abstract

The enantioselective excited-state quenching of rac-Tb(2,6-pyridinedicarboxylate) 3 3- [Δ,Λ,Tb(DPA) 3 3- ] by Δ-(-)-Ru- (1,10-phenanthroline) 3 2+ [Δ-Ru(phen) 3 2+ ] has been studied in aqueous solution (298 K) and in metbanol (298 and 255 K) as a function of solution ionic strength. The ionic strength of methanol and water solutions were controlled through the addition of NaBr
