Chiral or Luminescent Lanthanide Single-Molecule Magnets Involving Bridging Redox Active Triad Ligand
The reactions between the bis(1,10-phenantro[5,6-b])tetrathiafulvalene triad (L) and the metallo-precursors Yb(hfac)<sub>3</sub>(H<sub>2</sub>O)<sub>2</sub> (hfac<sup>−</sup> = 1,1,1,5,5,5-hexafluoroacetylacetonato anion) and Dy(facam)<sub>3</...
