协调角度和刚性的细微差异导致高度相似的单个组件在金属介导组装时自恋自分类。在金属介导的自组装中,配位角和刚度的细微差异导致了具有相同配位基序的单个组分之间的高保真分选。高度相似的配体与Fe(ii)离子和2-甲酰基吡啶结合后,刚性和内配位角变化极小,可实现自恋自分选。在一个烧瓶中,三种不同的核心配体(和33种总组分)的混合物可以精确地控制选择性、顺序的笼形形成,不同之处在于一个不参与金属配位过程的基团的杂交。
Subtle differences in coordination angle and rigidity lead to narcissistic self-sorting between highly similar individual components upon metal-mediated assembly. Subtle differences in ligand coordination angle and rigidity lead to high fidelity sorting between individual components displaying identical coordination motifs upon metal-mediated self-assembly. Narcissistic self-sorting can be achieved between highly similar ligands that vary minimally in rigidity and internal coordination angle upon combination with Fe(ii) ions and 2-formylpyridine. Selective, sequential cage formation can be precisely controlled in a single flask from a mix of three different core ligands (and 33 total components) differing only in the hybridization of one group that is uninvolved in the metal coordination process.
