摘要

本文為周C_(60)碳簇化合物做官能基，與3-胺基丙烯基固定相在甲苯下反應成一C_(60)碳簇固定相，此固定相可藉著IR光譜、固態^(13)CNMR、^(29)SiNMR、及元素分析鑑定其結構及表面覆蓋值，在正相層析中此產品鹵化芳香物有良好之分離效果，其中對多氯苯芳香化合物或多氯聯苯系列之毒性化合物，可藉由溶質與C_(60)-fullerene-phase固定相間之π~π interaction或charge transfer作用，將此類化合物作選擇住之分離，此對該系列之毒性物質在鑑定上有很大幫助。此外，本文用Amino-phase所測得之結果與該固定相結果作比較，發現在C_(60)-fullerene-phase固定相上K_1較Amino-phase上K_(11)值之選擇性比值(K_1/K_(11))大1.11~3.92倍。

C_(60)-fullerene stationary phase was prepared by the reaction of C_(60) and 3-aminopropylsilyl bonded silica in the presence of dry toluene as reaction solvent, The structure and surface coverage might be comfirmed by IR, solid state ^(13)CNMR, ^(29)SiNMR and element analysis. Liquid chromatography of this packing material was examined to have better performance for the separation of haloaromatics in normal phase condition. Especially, some toxic and harmful substances such as polychlorobenzenes or polychlorobiphenyls could be effectively separated by means of the π-π interaction or charge transfer interaction between C_(60)-fullerene stationary phase and solutes. In addition, capacity factors (K values) of all tested haloaromatics retained on this phase were found to be 1.11-3.92 folds stronger than those retained on 3-aminopropyl phase, while a commercial 3-aminopropyl stationary phase was used for comparison.
