performed by natural molecular machines with synthetic systems soluble in organic solvents. In efforts toward analogous systems working in water, we show that guest molecules can be exchanged in the synthetic macrocycle cucurbit[7]uril by involving kinetic traps, and in such a way as modulating energy wells and kinetic barriers using pH, light, and redox stimuli. Ditolyl‐viologen can also be exchanged
分子机器本质上无处不在,并且通过消耗燃料来产生适当的功而失去平衡。化学家最近擅长模仿天然分子机器在有机溶剂中可溶解的合成系统所完成的出色工作。在努力使类似系统在水中工作的过程中,我们证明了客体分子可以通过参与动力学陷阱而在合成的大环葫芦科[7] uril中进行交换,并且可以通过使用pH,光和氧化还原来调节能井和动力学屏障。刺激。Ditolyl-viologen也可以使用最佳的动力学阱进行交换,并与藻酸盐连接,从而提供可响应pH值的蓝色荧光水凝胶。具有可调的速率和对相关来宾的绑定常数,
