factors that govern recognition events at the molecular level represents a daunting challenge in our quest to master the art of pre-programmed molecular assemblies. In this context, we present the molecular architectonics of thoughtfully designed amino acid appended functional molecules 1–5. Naphthalenediimide (NDI) and pyrene were employed as functional modules due to their unusual topological shape similarity
阐明在分子水平上控制识别事件的复杂因素是我们寻求掌握预编程分子组装艺术的一项艰巨挑战。在这种情况下,我们展示了精心设计的氨基酸附加功能分子 1-5 的分子结构。萘二亚胺(NDI)和芘由于其不寻常的拓扑形状相似性以及互补的π-酸性和π-碱性特征分别被用作功能模块。此外,我们表明,与单组件系统中观察到的主要自分类组装相比,这种不寻常的功能模块的二元组在能量上有利于交替组装。此外,通过将微小的结构突变合并到 1-5 的氨基酸侧链中,我们成功地将它们的组件定制成定义明确的超分子结构,即超螺旋、扭曲的纳米带、纳米带、梳边纳米薄片和纳米片。借助实验和理论研究的详细分析已经对在分子水平上控制识别事件的因素产生了有趣的见解。
