Solvent-based synthetic methods of fullerene nano/microstructures are known to enhance and utilize unique optical and electrical properties of fullerene structures. Here, we report the systematic synthesis and characterization of various-shaped fullerene microcrystals using alcohols as antisolvents in drowning-out crystallization. The microcrystals are formed in one-, two-, and three-dimensional structures depending on the alcohol type, and the size and shape of the microcrystals are also varied by the C₆₀ concentration and the volume ratio of the solvents. X-ray diffraction patterns demonstrate that the crystalline structures differ from the chain lengths of alcohols. It is suggested that the formation mechanisms are driven by supersaturation related to the C₆₀ solubility in alcohols. This crystallization could allow for production of C₆₀ microcrystals with the desired shape and crystalline structure, leading to potential applications in optoelectronics and photoconducting devices.
