Macrocycles with Switchable exo/endo Metal Binding Sites

We report herein the synthesis and metal complexation properties of two macrocyclic hosts that contain two 2,2′-bipyridines and two urea groups. These hosts take advantage of the conformationally mobile 5,5′-positions of the bipyridines to give metal binding sites that are dynamic. By simple bond ro...
