Complexation between (O-methyl)-2,6-helic[6]arene and protonated pyridinium salts was investigated by H NMR, ESI-MS, and calculations. It was found that the host and the tested guests could form stable complexes and the binding and release process of the guests in the complexes could be reversibly controlled by acid-base stimulus. Notably, the switchable complexation could also be efficiently controlled by light stimulus in the presence of protonated merocyanine 1-MEH.
（O-甲基）-2,6-螺旋[6]芳烃与质子化吡啶盐的络合作用通过 H NMR、ESI-MS 和计算进行了研究。结果发现，主体和测试客体可以形成稳定的配合物，客体在配合物中的结合和释放过程可以通过酸碱刺激进行可逆控制。值得注意的是，在质子化变色氰 1-MEH 的存在下，光刺激也可以有效地控制这种可切换的络合作用。
