Chiral Nanoscale Metal-Organic Tetrahedral Cages: Diastereoselective Self-Assembly and Enantioselective Separation

Chiral Nanoscale Metal-Organic Tetrahedral Cages: Diastereoselective Self-Assembly and Enantioselective Separation

Cage rage: Chiral tetrahedral cages are diastereoselectively self‐assembled from enantiopure C2‐symmetric biphenyl bis(β‐diketonate) linkers and C3‐symmetric octahedral Fe3+ or Ga3+ ions (see picture; Fe purple, C blue, O red; cavity shown as an orange sphere). The porous polyhedra exhibit metal‐dep...

Zusammenfassung:Cage rage: Chiral tetrahedral cages are diastereoselectively self‐assembled from enantiopure C2‐symmetric biphenyl bis(β‐diketonate) linkers and C3‐symmetric octahedral Fe3+ or Ga3+ ions (see picture; Fe purple, C blue, O red; cavity shown as an orange sphere). The porous polyhedra exhibit metal‐dependent chiroptical behavior and act as hosts for the crystallization separation of racemic alcohols with up to 99.5 % ee.
