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。
