Driven Evolution of a Constitutional Dynamic Library of Molecular Helices Toward the Selective Generation of [2 × 2] Gridlike Arrays under the Pressure of Metal Ion Coordination
regioselectivity, occurring only at the extremities of the helical strands, allow one to perform directional terminal polymerization/depolymerization processes when starting with dissymmetric strands. A particular library is subsequently brought to express quantitatively [2 x 2] gridlike metallosupramolecular arrays in the presence of ZnII ions by component recombination generating the correct ligand from the dynamic
结构动力学、自组装和螺旋折叠控制在高效的 Sc(OTf)3/微波催化的螺旋寡腙链的转化中结合在一起,通过组件的组装、解离和交换产生高度多样化的互变成分动态库. ScIII 促进的交换的转亚胺型机制及其区域选择性仅发生在螺旋链的末端,允许从不对称链开始时进行定向末端聚合/解聚过程。随后,在 ZnII 离子存在的情况下,通过从相互转换链的动态组中生成正确配体的组分重组,一个特定的库被用于定量表达 [2 x 2] 网格状金属超分子阵列。
