Abstract：
This work presents the first example of the utilization of polar ester group functionalized pillar[6]arene (P6A-C10-OAc) as a stationary phase for capillary gas chromatographic (GC) separations. The statically coated P6A-C10-OAc column showed a high column efficiency of 5393 plates/m and moderate polar nature. Its resolving capability and retention behaviors were investigated for a mixture of 20 analytes and more than a dozen isomers from apolar to polar in nature. As evidenced, the P6A-C10-OAc column achieved high-resolution separations of all the analytes and good inertness. Importantly, it exhibited distinctly advantageous performance for high resolution of the challenging isomers of xylenes, diethylbenzenes, ethyltoluenes, and halobenzenes over the commercial HP-5 (5% phenyl dimethyl polysiloxane), HP-35 (25% phenyl dimethyl polysiloxane), and PEG-20M (polyethylene glycol) columns.
摘要：
这项工作提出了利用极性酯基官能化的柱状[6]芳烃（P6A-C10-OAc）作为毛细管气相色谱（GC）分离的固定相的第一个例子。静态涂覆的P6A-C10-OAc柱显示出5393板/m的高柱效率和中等极性性质。研究了20种分析物和十多种异构体的混合物的分辨能力和保留行为，这些异构体从本质上是非极性到极性。事实证明，P6A-C10-OAc柱实现了所有分析物的高分辨率分离和良好的惰性。重要的是,它表现出明显有利的性能，高分辨率的具有挑战性的异构体的二甲苯，二乙基苯，乙基甲苯，和卤代苯超过商业HP-5(5%苯基二甲基聚硅氧烷)，HP-35(25%苯基二甲基聚硅氧烷),和PEG-20M(聚乙二醇)柱。
