## Abstract Two charge‐transfer stationary phases were prepared by immobilizing __p__‐nitrobenzoic acid and naphthyl acetic acid onto silica. The nitrophenyl moiety and the naphthyl moiety were grafted to silica gel through the spacer of aminoalkyl silanes. The HPLC separation of C~60~, C~70~, and
## Abstract Chromatographic separation of C~60~ and C~70~ fullerenes was performed with phenylpropyl and three different methoxyphenylpropyl bonded phases in microcolumn liquid chromatography. The results indicate that the 3,4‐dimethoxyphenylpropyl phase possesses the best resolving power among the
