Abstract:
A new pair of multifunctional Zn(II)-Dy(III) enantiomers based on the chiral Schiff-base ligands [R,R-ZnLDy(H2O)(NO3)3] (1R2R-ZnDy) and [S,S-ZnLDy(H2O)(NO3)3] (1S2S-ZnDy) (H2L = phenol, 2,2'-[[(1R,2R/1S,2S)-1,2-diphenyl-1,2-ethanediyl]bis[(E)-nitrilomethylidyne]]bis[6-methoxy]) was synthesized and characterized. Magnetic studies indicate that 1R2R-ZnDy behaves as a single-molecule magnet. Enantiomers 1R2R-ZnDy and 1S2S-ZnDy show chiroptical activity and circularly polarized luminescence in the N,N-dimethylformamide (DMF) solution. The chiral Zn(II)-Dy(III) complexes display magnetic circular dichroism signals at room temperature. Accordingly, these complexes will inspire intriguing research on single-molecule magnets with circular polarization of luminescence activity and magneto-optic effects, which will give new clues to design multifunctional molecular magnetic materials.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
