We report the synthesis of a novel molecular switch based on a double-stranded ditopic ligand which operates through the CuII/CuI couple; the mononuclear cuprous and cupric complexes were characterised by absorption spectrophotometry; reversible motion of the copper ion between the two binding sites is driven by an auxiliary oxidation and reduction reaction; the rate-limiting steps of this translocation process were determined as well as the corresponding kinetic parameters.
我们报道了一种基于双链二位配体的新型分子开关的合成,该分子开关通过 CuII/CuI 电对起作用;采用吸收分光光度法对单核亚铜和单铜配合物进行了表征;两个结合位点之间铜离子的可逆运动是由辅助氧化和还原反应驱动的;确定了该易位过程的限速步骤以及相应的动力学参数。
