We report on the polymerization/depolymerization of chiral metallo-supramolecular assembly by CuI/CuII redox change. By combining a monotopic enantiopure ligand with a ditopic ligand of opposite configuration, ML2-type complexes are generated with chiral self-recognition or self-discrimination depending on the oxidation state of copper. In presence of CuI, the formation of heterochiral complexes is favored, thus generating dinuclear species whereas CuII advocates for the formation of homochiral species, namely, a mixture of mononuclear species and metallo-supramolecular polymeric species. Thus, cyclic voltammetry was used to study such a chirality-induced stimulus sensitive polymerization/depolymerization process.

氧化还原变化诱导手性金属超分子组装的聚合/解聚

我们报告了通过 Cu I /Cu II氧化还原变化进行手性金属超分子组装的聚合/解聚。通过将单位对映体纯配体与相反构型的双位配体结合,根据铜的氧化状态,产生具有手性自识别或自识别的ML 2型配合物。在 Cu I存在下,有利于形成异手性配合物,从而产生双核物种,而 Cu II主张形成同手性物种,即单核物种和金属超分子聚合物物种的混合物。因此,循环伏安法用于研究这种手性诱导的刺激敏感聚合/解聚过程。
