Homochiral DyIII complexes: By changing the ligand-to-metal ratio, enantiomeric pairs of a complex different nuclearity could be obtained. The mono- and dinuclear complexes exhibit characteristics single-molecule magnets slow magnetic relaxation processes. In addition, (see picture) ferroelectric behavior, thus representing first chiral polynuclear lanthanide-based with properties.

Abstract Amine‐functionalized bimetallic Fe/Ti‐based metal–organic frameworks (Fe/Ti‐MOF‐NH 2 ) were synthesized via the solvothermal method and used as photocatalysts activators for persulfate (PS)‐assisted visible light photocatalytic degradation of Orange II. Nearly 100% II was removed within 10 min in Fe/Ti‐MOF‐NH (3:1)/PS/Vis process, while only 10.7% 70.9% (3:1)/Vis (3:1)/PS processes min, respectively. Therefore, synergistic effect PS activation photocatalysis demonstrated by (3:1)...
