Supramolecular construction strategies have overwhelmingly relied on the principles of thermodynamic control. While this approach has yielded an incredibly diverse and striking collection of ensembles, there are downsides, most obviously the necessity to trade-off reversibility against structural integrity. Herein we describe an alternative "assembly-followed-by-fixing" approach that possesses the
超分子构建策略绝大多数依赖于热力学控制原理。虽然这种方法产生了令人难以置信的多样化和惊人的集合,但也有缺点,最明显的是需要在可逆性与结构完整性之间进行权衡。在本文中,我们描述了另一种“组装后固定”方法,该方法具有可逆自组装反应的高产率、原子效率优势,同时提供具有类似共价
水平的动力学稳健性的结构。我们选择在一系列 M2L3 螺旋和

配体的刚性导致较大的物种在能量上更受青睐,但我们能够在“
