Homochiral Dy₂ single-molecule magnets with strong magneto-optical Faraday effect and strong third-harmonic generation

Four pairs of homochiral Dy2 complexes were directionally prepared using homochiral β-diketone ligands {D-Htfc/L-Htfc = (+)/(−)-3-trifluoroacetyl camphor, D-Hpfc/L-Hpfc = 3-(perfluorobutyryl)-(+)/(−)-camphor} and hydrazone Schiff base bridging ligands {H2L1 = (E)-N'-(2-hydroxy-3-methoxybenzylidene)pyrazine-2-carbohydrazide, H2L2...
