Stepwise introduction of dipole blades into triptycenes: opening the variety of crystalline molecular packing modes

Abstract

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