成功地构建了一种基于乙二醇桥联吡啶和柱[5]芳烃的机械自锁假[1]轮烷。通过1H、2D NMR和HR-ESI-MS确证了假[1]轮烷的结构和自锁构象。研究发现，在稀溶液中，假[1]轮烷可以作为酸碱可控的双态分子穿梭体进行操作，而在浓溶液中，假[1]轮烷以二聚体的形式存在，可以从收缩态到伸展态进行操作。
A ethylene glycol bridged pyridine and pillar[5]arene based mechanically selflocked pseudo[1]rotaxane was constructed successfully. The structure and selflocked conformation of pseudo[1]rotaxane were confirmed by1H, 2D NMR spectrum and HR‐ESI‐MS. It was found that in dilute solution the pseudo[1]rotaxane could be operated as an acid/base‐controllable two state molecular shuttle while In concentrated solution, the pseudo[1]rotaxane existed as a dimer and could be operated from shrinking state to extension state.
