Abstract

Abstract : The combination of halogend bonds from PO and N-moieties with π-stacking leads to sort out R - and S -isomers into homoleptic, porous assemblies. Abstract : PO⋯X and N⋯X halogen bonds in combination with π-stacking interactions lead to the sorting of π-extended R - and S -isomers. Theoretical calculations point to a positive synergistic effect between the π-interactions and the halogen bonds to be the origin of such phenomena. As a result, enantiomeric building blocks form homoleptically connected quadrangular structures.
