Abstract

C₆₀–C₇₀ nanofibers (FNFs) were prepared using a modified liquid–liquid interfacial precipitation (LLIP) method in a pyridine solution of C₆₀–C₇₀ soot and isopropyl alcohol (IPA) under illumination with white light in the region of 300–700 nm. The composition of the C₆₀–C₇₀ FNFs was analysed by high-pressure liquid chromatography. It is found that the concentration of C₇₀ in the C₆₀–C₇₀ FNFs is decreased with an increase of irradiation time in the C₆₀–C₇₀–pyridine solution. Regarding the morphology aspect, polarizing optical microscope (POM) and scanning electron microscope (SEM) were used and changing the irradiation time may well be a method to control the length or diameter of those fibers. In an analysis of the mechanism, it was speculated that the charge transfer (CT) complexes between fullerenes C₆₀, C₇₀ and pyridine that could be excited by photons was an explanation for this phenomenon.
