Coordination driven axial chirality in a microporous solid assembled from an achiral linker via in situ C–N coupling

Abstract

Metal mediated in situ C–N coupling between 4,4′-azobipyridine and disodium-trans-glutaconate at room temperature has formed a new multifunctional linker ZZ-dhpe which subsequently self-assembles with Zn(II) or Cd(II) resulting in a chiral or an achiral metal–organic framework, respectively, depending on its different coordination modes.
