A new cationic molecular turnstile based on a P(V) porphyrin backbone bearing two pyridyl interaction sites, one at the meso position of the porphyrin and the other on the handle connected to the porphyrin through P–O bonds, was designed and synthesized. The dynamic behavior of the turnstile 2, investigated by 1D and 2D 1H NMR techniques, showed that in the absence of an effector, the turnstile is
设计并合成了一种新的基于P(V)卟啉骨架的阳离子分子旋转栅,该骨架带有两个吡啶基相互作用位点,一个在卟啉的内消旋位置,另一个在通过P–O键与卟啉连接的手柄上。通过1D和2D 1 H NMR技术研究的旋转栅2的动态行为表明,在没有效应子的情况下,旋转栅处于打开状态,并且转子(手柄)绕定子自由旋转(卟啉主链)。在存在外部效应器(例如Ag +阳离子或H +)的情况下,旋转栅将切换至其闭合状态2 -Ag +和2 -H +, 分别。锁定/解锁过程是可逆的,在银锁定旋转栅的情况下,可以通过添加Et 4 NBr沉淀AgBr来实现;在质子锁定旋转栅的情况下,可以通过添加Et 3 N来实现。
