由含酯巴比妥萘组成的亚稳超分子氢键簇通过氢键模式的重排转变为结晶纳米片。证明了酯基在结晶氢键模式中的参与，指导我们进行新的分子设计，可以提供具有软分子和硬分子包装的超分子多晶型。
Transformation of metastable supramolecular stacks of hydrogen-bonded rosettes composed of an ester-containing barbiturated naphthalene into crystalline nanosheets occurs through the rearrangement of hydrogen-bonding patterns. The involvement of the ester group in the crystalline hydrogen-bonded pattern is demonstrated, guiding us to a new molecular design that can afford supramolecular polymorphs with soft and hard molecular packing.
