Solvated microcrystals of C 60 and C 70 prepared by co‐solvent precipitation with methylbenzenes and 2‐propanol as good and poor solvents, respectively, display enhanced photoluminescence over pristine fullerenes. Monodisperse nonspherical colloids with diverse morphology including hexagonal platelets and rods with facets, hollow ends, or ‘flower‐like’ cross‐sections, are grown based on the concentration and injection volume of the fullerene solution.
