Stepwise Introduction of Dipole Blades into Triptycenes: Opening Variety of the Crystalline Molecular Packing Modes

Abstract

We report that stepwise introduction of difluorophenylene as dipolar blades into triptycenes diversifies the intermolecular packing modes in crystals. Single crystal XRD study revealed that changing the number of dipoles in triptycene tunes the intermolecular packing from two dimensional intermeshed to helical structures, offering a novel insight for engineering triptycene-based supramolecular materials.
