Abstract：
A six-cyclic crown ether-type pillar[5]arene was synthesized, and the five ethylene oxide loops were located outside the cavity and not affected by temperature changes which was confirmed by variable-temperature NMR experiment in DMSO-d6 and CDCl3 and 2D 1H-1H NOESY experiment in CDCl3. The six-cyclic pillar[5]-crown also showed greater binding ability of host-guest with bis(pyridinium) derivatives than conventional alkoxy pillar[5]arenes that illustrated through 1H NMR titration spectroscopic experiment in acetone-d6/CDCl3 (1:1) and UV-vis titration experiments in CHCl3 at room temperature. The five benzocrown ethers at the periphery were able to bind metal cations by 1H NMR titration spectroscopic experiment in CD2Cl2/methanol-d4(9:1).
摘要：
合成了一种六环冠醚型支柱[5]芳烃，并且五个环氧乙烷回路位于腔外，不受温度变化的影响，这通过DMSO-d6和CDCl3中的变温NMR实验以及CDCl3中的2D1H-1HNOESY实验得到了证实。六环柱[5]-冠还显示出比常规烷氧基柱[5]芳烃更高的主客体与双（吡啶）衍生物的结合能力，这通过1HNMR滴定光谱实验在丙酮-d6/CDCl3（1：1）和室温下在CHCl3中进行的UV-vis滴定实验进行了说明。通过在CD2Cl2/甲醇-d4（9：1）中的1HNMR滴定光谱实验，外围的五个苯并冠醚能够结合金属阳离子。
