A silica-bound -butylpyrogallol[4]arene chromatographic stationary phase was prepared and characterised by thermogravimetric analysis, scanning electron microscopy, NMR and mass spectrometry. The chromatographic performance was investigated by using C and C fullerenes in reverse phase mode via flash column and high-pressure liquid chromatography (HPLC). The resulting new stationary phase was observed to demonstrate size-selective molecular recognition as postulated from our in-silico studies. The silica-bound -butylpyrogallol[4]arene flash and HPLC stationary phases were able to separate a C- and C-fullerene mixture more effectively than an RP-C stationary phase. The presence of toluene in the mobile phase plays a significant role in achieving symmetrical peaks in flash column chromatography.
一种键合在硅胶上的 -丁基苯并[g,h,i]苝色谱固定相通过热重分析、扫描电子显微镜、NMR 和质谱进行了制备和表征。通过反相模式的闪蒸柱和高效液相色谱（HPLC），使用 C 和 C 富勒烯对色谱性能进行了研究。从我们的计算机模拟研究中可以推断出，所得的新型固定相表现出尺寸选择性的分子识别。硅胶键合的 -丁基苯并[g,h,i]苝闪蒸和 HPLC 固定相比 RP-C 固定相更有效地分离 C 和 C 富勒烯混合物。流动相中甲苯的存在对在闪蒸柱色谱中获得对称峰起着重要作用。
