A new type of fullerene-containing polysiloxane was synthesized by reacting [60]fullerene with azidopropyl polysiloxane directly. The polysiloxanes have been used successfully as stationary phases for capillary gas chromatography. They displayed high column efficiency, wide operational temperature and high thermostability, and exhibited unique selectivity for many organic substances, such as alkanes, alcohols, ketones and aromatic compounds. The stationary phase was especially suitable for separation of high boiling-point compounds like polycyclic aromatic hydrocarbons and phthalic esters, etc. It was also found that some alcoholic or aromatic positional isomers could be well separated on the column. The influence of the fullerene content on the separation was also investigated.
通过使[60]富勒烯与叠氮丙基聚硅氧烷直接反应，合成了一种新型的含富勒烯聚硅氧烷。该聚硅氧烷已成功用作毛细管气相色谱的固定相。它们具有高柱效、宽操作温度范围和高热稳定性，并且对许多有机物质，如烷烃、醇类、酮类和芳香族化合物表现出独特的选择性。该固定相特别适用于分离多环芳烃和邻苯二甲酸酯等高沸点化合物。还发现一些醇类或芳香族位置异构体在该柱上能够得到很好的分离。同时也研究了富勒烯含量对分离的影响。
