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.
由含酯基巴比妥酸萘组成的氢键连接的玫瑰花结的亚稳超分子堆叠体转变为结晶纳米片是通过氢键模式的重排实现的。酯基参与结晶氢键模式得到了证实，这引导我们进行新的分子设计，从而获得具有软分子堆积和硬分子堆积的超分子多晶型物。
