An arm modification strategy, by replacing relatively rigid, electron-deficient side arms with flexible ether chain arms and linking them onto a tetraoxacalix[2]arene[2]triazine skeleton, was utilized to design an artificial molecular hourglass. The planar bilayer experiments confirmed the unimolecular channel mechanism and suggested reversed ion selectivity from the previously reported anion selectivity to weak cation selectivity.
一种臂修饰策略被用于设计一种人工分子沙漏，该策略是用柔性醚链臂取代相对刚性、缺电子的侧臂，并将它们连接到四氧杂杯[2]芳烃[2]三嗪骨架上。平面双层实验证实了单分子通道机制，并表明离子选择性与之前报道的阴离子选择性相反，变为弱阳离子选择性。
