Abstract

Luminescence quenching of Eu(fod)3(fod = 6,6,7,7,8,8,8-heptafluoro-2,2-dimethyl-3,5-octanedionate) by a Cu(ii) macrocycle was studied at 25, 35 and 45 °C by steady-state and flash luminescence techniques, varying the Cu(ii) concentration between 0.2 and 20 mM. Experimental variation of the observed rate constant with the quencher concentration is rationalized in terms of a mechanism involving the quenching of two unequilibrated species by the Cu(ii) macrocycle.
