Abstract
Post-self-assembly modifications of a discrete metal-organic supramolecular structure have been developed. Such modifications allow the properties of the self-assembled supramolecular species to be changed in a simple and efficient manner (>90% yield). Initiated by the application of chemical stimuli, the post-self-assembly modifications described herein result in three distinct changes to the supramolecular system: an individual building-block component change, an overall structural modification, and a functional evolution of a [6+4] metal-organic supramolecular structure. The three modifications have been carefully examined by a range of characterization methods, including NMR and UV-vis spectroscopy, electrospray ionization mass spectrometry, pulsed field gradient spin echo NMR measurements, electrochemical analysis, and computational simulations.
摘要
已开发出离散金属有机超分子结构的自组装后修饰。这些修饰可以以简单有效的方式改变自组装超分子物质的性质（产率>90%）。受化学刺激的应用的启发，本文所述的自组装后修饰导致超分子系统发生了三个明显的变化：单个构建块组件的变化、整体结构的修饰以及[6+4]金属有机超分子结构的功能演变。通过一系列表征方法，包括 NMR 和 UV-vis 光谱、电喷雾电离质谱、脉冲场梯度自旋回波 NMR 测量、电化学分析和计算模拟，对这三种修饰进行了仔细的检查。
