Dioxygen binding solely through non-covalent interactions is rare. In living systems, dioxygen transport takes place iron or copper-containing biological cofactors. Specifically, a reversible covalent interaction is established when O binds to the mono or polynuclear metal center. However, O stabilization in the absence of covalent bond formation is challenging and rarely observed. Here, we demonstrate a unique example of reversible non-covalent binding of dioxygen within the cavity of a well-defined synthetic all-Cu(i) tetracopper cluster.
仅通过非共价相互作用进行的双氧结合很少见。在生命系统中，双氧运输通过含铁或含铜的生物辅因子进行。具体而言，当O与单核或多核金属中心结合时，会形成可逆的共价相互作用。然而，在不形成共价键的情况下实现O的稳定化具有挑战性，且很少被观察到。在这里，我们展示了一个独特的例子，即在一个明确的全铜（I）四核铜簇的腔内发生双氧的可逆非共价结合。
