A couple of self-folding A-D-A guests were synthesized, and it was found that the guests could be included by the pentiptycene-based tweezer-like hosts to form stable 1:1 complexes in solution, which have been evidenced by the 1H NMR, ROESY 2D NMR and ESI MS spectra. Moreover, a potassium ion-controlled switchable process between the host and the self-folding guest was further achieved.
合成了一些自折叠的ADA客体,发现客体可以被基于五萜烯的镊子样主体所包含,从而在溶液中形成稳定的1:1络合物,这已经通过1 H NMR进行了证明, ROESY 2D NMR和ESI MS光谱。而且,进一步实现了宿主和自折叠客体之间钾离子控制的可切换过程。
