We report a quite flexible naphthol-based cage (so-called "naphthocage") which adopts a self-inclusion conformation in its free state and is able to bind singly charged organic cations extremely strongly ( K > 10 M). Ion-selective electrodes prepared with this naphthocage show a super-Nernstian response to acetylcholine. In addition, the highly stable complex (10 M) between ferrocenium and the naphthocage can be switched electrochemically, which lays a basis for its application in stimuli-responsive materials.
我们报道了一种相当灵活的萘基笼（所谓的“萘笼”），它在自由状态下采用自包含构象，并且能够非常强烈地结合单价有机阳离子（K > 10 M）。用这种萘笼制备的离子选择性电极对乙酰胆碱表现出超 Nernst 响应。此外，铁氰化钾与萘笼之间的高稳定配合物（10 M）可以通过电化学方式进行切换，这为其在响应性材料中的应用奠定了基础。
