An anionic three‐way switch: A bipyridyl bis(urea)‐based anion receptor that is highly selective for dihydrogenphosphate demonstrates spectroscopically distinct anion‐bound conformations toward halides and select oxoanions. 1H NMR studies show the differing anion‐induced conformations are reversible allowing this system to function as a three‐way molecular switch.
阴离子三向开关:一种对磷酸二氢具有高度选择性的基于联吡啶双(尿素)的阴离子受体显示出对卤化物和选择氧阴离子的光谱上不同的阴离子结合构象。1 H NMR 研究表明,不同的阴离子诱导构象是可逆的,使该系统可以作为三向分子开关。
