| A mechanistic model for enantioselective excited-state quenching kinetics is described for systems in which quenching occurs via electronic energy transfer between chiral lanthanide (donor) and transition-metal (acceptor) complexes in solution. This mechanism includes contributions from lanthanide enantiomer interconversion (or racemization), diffusion, activation, and electronic energy-transfer processes; and these contributions are probed experimentally by utilizing time-resolved chiroptical luminescence (TR-CL) measurement techniques. The luminophores of interest are tris-terdentate chelate structures in which either Eu... |
