Abstract

Crystalline precipitates composed of C₆₀ and C ₆₀(6,7-dimethoxytetralin) were prepared by the liquid-liquid interfacial precipitation method and examined by Raman spectroscopy and transmission electron microscopy (TEM). The as-prepared C₆₀ nanotubes (C₆₀NTs) dried in air exhibited a Raman spectrum showing a linearly polymerized structure, and a part of them turned to van der Waals polymers after drying in air. On the other hand, the C₆₀NTs dried in air turned to a polymerized structure by irradiation of UV light. The whiskers prepared by use of C₆₀ (6,7- dimethoxytetralin) showed an A_g(2) peak of 1460 cm^-1 suggesting a polymerization of C₆₀ and a Raman spectrum with sharp and clearly splitted peaks in the range of 200-800 cm ^-1, indicating a good crystallinity.
