In this work, the fabrication, synthesis, and characterization of a new stationary phase based on an amphiphilic pillar[6]arene (P6A-C10-2NH) for gas chromatographic analyses are reported. The gas chromatography (GC) column prepared with P6A-C10-2NH stationary phase exhibited a medium polarity, an efficiency of 3219 plates/m, and unmatched resolving capabilities toward chloroaniline, bromoaniline, iodoaniline, and toluidine isomers. Furthermore, the P6A-C10-2NH column showed excellent repeatability with maximum relative standard deviations equal to 0.02, 0.07, and 2.56% for run-to-run, day-to-day, and column-to-column, respectively, demonstrating a great potential as a new stationary phase in separation science.
本工作报道了一种新型基于两亲性杯[6]芳烃（P6A-C10-2NH）的固定相的制备、合成和表征，用于气相色谱分析。用 P6A-C10-2NH 固定相制备的气相色谱（GC）柱具有中等极性，效率为 3219 板/米，对氯苯胺、溴苯胺、碘苯胺和甲苯胺异构体具有无与伦比的分辨能力。此外，P6A-C10-2NH 柱具有出色的重现性，运行间、日间和柱间的最大相对标准偏差分别等于 0.02、0.07 和 2.56%，表明其在分离科学中作为新型固定相具有巨大潜力。
