Crystallization method of flower-shaped fullerenes and flower-shaped fullerenes manufactured therefrom

摘要

The present invention comprises the steps of preparing a C ₆₀ solution or C ₇₀ solution by adding a good solvent to the C ₆₀ powder or C ₇₀ phosphorus fullerene powder to dissolve (first step); Filtering the solution and adjusting the concentration (second step); Preparing a precursor solution by mixing the adjusted C ₆₀ solution or C ₇₀ solution (third step); Adding the precursor solution to the subsolvent to react to form a flower fullerene crystal (fourth step); And it relates to a floral fullerene crystallization method and the resulting floral fullerene crystals comprising the step of filtering the fullerene crystals (step 5). Thus, the shape and shape of the fullerene crystals produced can be controlled using solution phase crystallization. Fullerene crystals having various shapes and structures can be prepared using a solution phase crystallization method, and in particular, fullerene crystals can be produced in a flower shape according to the type of solvent and the addition ratio.
