Abstract

Abstract Based on a first example of an allosteric hemicarcerand (1) we prepared four new 2, 2′-bipyridines that carry resorcinarene moieties in a highly convergent manner. Upon coordination to suitable transition metal ions or their complexes these compounds undergo conformational changes in a way that they switch between “open” and “closed” forms (2, 3, and 4) or vice versa (5), thus, bringing together or separating the two functional moieties ...
