摘要：

We report the synthesis of lanthanide complexes supported by enantiopure N,N'-bis(methylbipyridyl)bipyrrolidine and subsequent characterization through luminescence studies. Complexes of this ligand with the visibly emissive lanthanides Sm, Eu, Tb, and Dy are luminescent (phi(f) of <= 0.32) and demonstrate strong preferential emission of circularly polarized light in all four cases (vertical bar g(lum)vertical bar of <= 0.26). Notably, all four possess at least one transition with a vertical bar g(lum)vertical bar of >0.2, and the strongest preferential emission is measured from the complexes of Sm and Dy.
