    Abstract

    © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. The reaction of the chiral dipeptide glycyl-L(S)-glutamate with Co<sup>II</sup> ions produces chiral ladders that can be used as rigid 1D building units. Spatial separation of these building units with linkers of different lengths allows the engineering of homochiral porous MOFs with enhanced pore sizes, pore volumes, and surface areas. This strategy enables the synthesis of a family of isoreticular MOFs, in which the pore size dictates the enantioselective adsorption of chiral molecules (in terms of their size and enantiomeric excess).
