Morphological control of C₆₀ by a fullerodendron-assisted approach

Control over the morphology of C₆₀ particles has been achieved through the use of fullerodendron during crystallization. Various comparison experiments showed that fundamental experimental parameters, such as the molar ratio of fullerodendron and the concentration of C₆₀, played important roles in the morphological control of C₆₀ particles. A lower molar ratio of fullerodendron favors whisker-like products, whereas a higher molar ratio generally leads to the formation of spherical products. Microspheres of C₆₀ can be synthesized by the introduction of self-assembling fullerodendron. Scanning electron microscope (SEM) and high-resolution transmission electron microscope (HRTEM) were used to characterize the products.
