Dual-Action Acid/Base- and Base/Acid-Controllable Molecular Switch
摘要:
We report a molecular switch that not only can be switched between its complexed and decomplexed states through the sequential addition of an acid and a base (NH(4)(+) and Proton Sponge, respectively) but also can be operated equally through the sequential addition of basic and acidic reagents (Et(2)NH and TFA, respectively).
We have synthesized a new molecular switchâbased on a macrocycleâclip complexâwhose switching behavior not only can be controlled through the use of either K+â[2,2,2]cryptand or NH4+âEt3N systems but also provides color changes that are visible to the naked eye; consequently, this system operates as a two-input NOR functioning molecular logic gate.
我们合成了一种新的分子开关,它基于一种大环螯合物,其开关行为不仅可以通过使用 K+â[2,2,2]隐烷或 NH4+âEt3N 系统来控制,而且还能提供肉眼可见的颜色变化;因此,该系统可以作为一个双输入 NOR 功能分子逻辑门来运行。
A Macrocycle/Molecular-Clip Complex that Functions as a Quadruply Controllable Molecular Switch
synthesis of a molecular clip with TTF side-walls and its binding behavior towards electron-deficient guests, namely the formation of macrocycle/molecular-clip supramolecular complexes in solution. Four different sets of external stimuli--the K(+)/[2.2.2]cryptand, NH(4) (+)/Et(3)N and (p-BrPh)(3)NSbCl(6)/Zn pairs, and heating/cooling cycles-control the movement of this molecularswitch between its threaded
