Anion switches: A bistable self‐assembled metal–organic macrocycle undergoes intramolecular conformational motion that is switched reversibly with anions by multiple hydrogen‐bonding interactions (see picture; Pd orange, N blue, O red). The molecular bowl fixed with a nitrate anion could be freed to a partial chair by adding a tetraphenylborate anion.
阴离子开关:一个双稳态自组装金属有机大环分子经历分子内的构象运动,并通过多种氢键相互作用与阴离子可逆地转换(见图; Pd橙色,N蓝色,O红色)。通过添加四苯基硼酸根阴离子,可以将固定有硝酸根阴离子的分子碗释放到部分椅子上。
