The art of stacking: structural folding and self-assembly of branched π-conjugation assisted by O–H⋯O and C–H⋯F hydrogen bonds†‡
Abstract
An intimate interplay of O–H⋯O/C–H⋯F hydrogen bonds and π–π stacking interactions allows a phenyleneethynylene-based dendritic molecule to fold and self-assemble into two distinctively different molecular crystals as pseudopolymorphs.
