shut as necessary. Such second-sphere complexation can allow considerable control to be exerted on photocatalysis, electrocatalysis, and luminescent sensing involving polypyridineRu(II) compounds. The capturing states of hosts are symmetry-matched to guests for selective binding and display submicromolar affinities. A perching complex, which is an intermediate state between capturing and releasing states
从基态/激发态开始的
水中电子/质子转移是
化学的基本反应。一类标志性分子——聚
吡啶钌(II)——的这些反应现在是通过用形状可切换的宿主捕获或释放其中的三个来控制的。主体壁的可逆竖立或倒塌允许这种可切换性。通过
金属配合物的包容性结合,一些反应速率被高达 120 的因子抑制。这将纳米配位
化学放在一个可以根据需要打开或关闭的盒子中。这种第二球络合可以对涉及聚
吡啶钌(II)化合物的光催化、电催化和发光传感进行相当大的控制。宿主的捕获状态与客体对称匹配,用于选择性结合并显示亚微摩尔亲和力。
