Abstract

The temperature dependence of the steady-state luminescence dissymmetry ratio, glum, has been measured for racemic Eu(III) complexes containing the terdentate ligands dipicolinate and phenylethynyl-dipicolinate. As the temperature is increased, the magnitude of the dissymmetry ratio for these species decreases due to racemization occurring during the excited state lifetime. The temperature dependence of glum is analyzed by a non-linear curve-fitting technique to determine the activation energies for the interconversion of the enantiomers. Comparison is made with previous measurements involving time-resolved circularly polarized luminescence.
