Abstract: | 我們發現寡聚乙二醇基團可藉由鈉離子模板穿隧大環分子BPX26C6,並在無溶劑的條件下合成其相對應的[2]車輪烷。在此類[2]車輪烷中,具有四甘醇基團者可表達分子開關的行為,利用加入或移除鉀離子,可使大環分子選擇性地在四甘醇基團或氨基甲酸酯(Carbamate)基團間來回移動。 Threading of di-, tri-, and tetra(ethylene glycol) through the macrocycle BPX26C6 in the presence of templating Na+ ions was proven by the synthesis of the corresponding [2]rotaxanes under solvent-free conditions. Among them, a [2]rotaxane featuring both tetra(ethylene glycol) and carbamate stations behaves as a molecular switch that can be controlled reversibly through the application of the KTFPB/[2.2.2]cryptand reagent pair. |
