We show distinct CH-π interactions and assembly pathways for the amphiphile -(fluorenylmethoxycarbonyl)-galactosamine and its epimer -(fluorenylmethoxycarbonyl)-glucosamine. These differences result in the formation of supramolecular nanofibrous systems with opposite chirality. Our results showcase the importance of the carbohydrates structural diversity for their specific biointeractions and the opportunity that their ample interactome offers for synthesis of versatile and tunable supramolecular (bio) materials.
我们展示了 -(芴甲氧羰基)-半乳糖胺及其差向异构体 -(芴甲氧羰基)-葡萄糖胺这两种两亲分子的独特 CH-π 相互作用和组装途径。这些差异导致了具有相反手性的超分子纳米纤维系统的形成。我们的研究结果展示了碳水化合物结构多样性对于其特定生物相互作用的重要性，以及其丰富的相互作用组为合成多功能和可调谐的超分子（生物）材料提供的机会。
