A chiral bivalve : Upon insertion of zinc ions, the 3,3′‐bis(N‐confused porphyrin) adopts a bent transoid structure with homochiral subunits that are capable of the supramolecular binding of alcohols. The introduction of a dianionic ligand of defined configuration results in the racemic mixture being converted into a pure enantiomer (see picture; tart=tartrate dianion) as determined by circular dichroism studies.
