Abstract
AbstractWe report the specific intermolecular interactions on C70‐fullerene. A newly developed silica‐monolithic capillary column, which was modified with C70‐fullerene via a particular thermal reactive molecule, perfluorophenyl azide, provided a selective retention behavior toward polycyclic aromatic hydrocarbons in liquid chromatography. Especially, a hemispherical molecule, i. e., corannulene, was significantly retained on this C70‐fullerene column. Results of the computer simulation of the molecules suggested that the specific interaction might be caused by the deflection of the π‐electrons‐density in C70‐fullerene. Furthermore, the absorption spectrometry also indicated that the absorption spectra of C70‐fullerene with/without corannulene were dramatically changed by the specific interaction, whereas no spectrum differences were observed with C60‐fullerene.
