Remarkably Selective Binding, Behavior Modification, and Switchable Release of (Bipyridine)₃Ru(II) vis-a-vis (Phenanthroline)₃Ru(II) by Trimeric Cyclophanes in Water.

ABSTRACT: A recurring dream of molecular recognition is to create receptors that distinguish between closely related targets with sufficient accuracy, especially in water. The more useful the targets, the more valuable the dream becomes. We now present multianionic trimeric cyclophane receptors with a remarkable ability to bind the iconic (bipyridine)₃Ru(II) (with its huge range of applications) while rejecting the nearly equally iconic (phenanthroline)₃Ru(II). These receptors not only selectively capture (bipyridine)₃Ru(II) but also can be redox-switched to release the guest. 1D- and 2D(ROESY)-NMR spectroscopy, luminescence spectroscopy, and molecular modeling enabled this discovery. This outcome allows the control of these applications, e.g., as a photocatalyst or
