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 Z-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.
