摘要
(Figure Presented) Cage rage: Chiral tetrahedral cages are diastereoselectively self-assembled from enantiopure C2-symmetric biphenyl bis(β-diketonate) linkers and C3-symmetric octahedral Fe3+ or Ca3+ 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. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
