Use of the fluorescence of lanthanide complexes to study the kinetics of a ligand-transfer reaction
Abstract
The kinetics of the transfer of a 2,2′6′,2″-terpyridyl (terpy) molecule from [Eu terpy3]3+ to Tb3+ in nitromethane solution have been determined by a study of the fluorescence of the europium complex; the reaction is first order in [Eu terpy3]3+, independent of the Tb3+ concentration, and has t½= 6·1 min. at 2·8°.
