摘要
以不同长度的亚烷基二胺单元作为柱[5]芳烃边缘侧链的一系列柱[5]单酰胺衍生物,在氯仿中能够形成准[1]轮烷.基于这一中间体准[1]轮烷的合成,通过柱[5]单酰胺衍生物和双水杨醛的缩合反应,成功构建了8个柱芳烃的机械自锁分子(MSMs),即双-[1]轮烷.通过多种方法详细地对新合成的双-[1]轮烷进行了研究,包括1HNMR, 13CNMR,2D NOESY NMR和MS分析,发现这类新型MSMs与Cu2+有较强的识别作用,两者之间以1∶2进行络合.
A series of pillar[5]arene monoamide derivatives with different lengths of alkylenediamine unites as the side chains on the pillar[5]arene’s rim can form pseudo[1]rotaxanes. Thus, based on the construction of this intermediate of pseudo[1]rotaxane, eight pillar[5]arene-baed mechanically interlocked molecules(MIMs) of bis-[1]rotaxane were successful constructed through condensation reaction of pillar[5]arene monoamide derivative and salicylaldehyde. The newly synthesized bis-[1]rotaxane was investigated in detail by various methods, including 1 H NMR, 13 C NMR, 2 D NOESY NMR and MS analysis. It was found that this kind of MIMs has a strong recognition effect with Cu2+, which complexed by 1∶2.
