Abstract: | 我們合成了一個含有胍基(Guanidinium)的客體分子,並發現其可與適當的大環分子在低極性溶液中形成穩定的錯合物。為證明此一錯合物主要是以準車輪烷形式存在溶液中,我們以「穿透後封鎖法」合成出一個同時具有胍基和吡啶(Pyridinium)二個辨識中心的車輪烷分子並成功地藉著改變溶劑極性及加入/移除鹵素離子或醋酸根離子來加以控制大環分子和胍基分子間的錯合與解離,進而操作分子開關的移動異構化(translational isomerization)。 We have demonstrated that guanidinium ions can thread through the cavity of BPX26C6 to form [2]pseudorotaxane-like complexes in low-polarity solvents. A [2]rotaxane derived from this new recognition system functions as a molecular switch, in which translational movement of macrocyclic component can be controlled two ways: through changes in solovent polarity and through exchanges of the counter anions. |
