Abstract
Fullerene compounds such as C60 are dissolved into solvents such as toluene in concentration of 1.times.10-3 mol/L or more. When the solution is coagulated, fullerene associated bodies are formed. After the re-dissolution of the solution, the associated bodies are excited by laser beam, and the resultant is cluster compounds of fullerene having specific number of monomers, such as 23 and 53. The cluster is stable and separable from the solution.
