Glucose Binding Drives Reconfiguration of a Dynamic Library of Urea?Containing Metal–Organic Assemblies

A bis-urea-functionalized ditopic subcomponent assembled with 2-formylpyridine and FeII , resulting in a dynamic library of metal-organic assemblies: an irregular FeII4 L6 structure three FeII2 L3 stereoisomers: left- right-handed helicates meso-structure. This reconfigured response to the addition monosaccharide derivatives, which served as guests for specific members, rate saccharide mutarotation was also enhanced by library. The (P) enantiomer helical bound ?-D-glucose selectively over ?-D-glucose. As consequence, collapsed into (P)-FeII2 helicate following glucose addition. ?-D-glucose likewise transformed ?-D-anomer during equilibration binding. Thus, (P)-3 amplified each other product mixture, libraries geared together single equilibrating system.
