| Outline of Final Research Achievements |
Graphite laser ablation was conducted and the products carried by argon gas flow were captured by an organic solvent. Then the solution was analyzed with UV absorption spectroscopy and HPLC, to identify and evaluate the yields of carbon-rich species. Special care was focused on monocyclic ring clusters. First, we confirmed that the soluble C60 was formed by the room temperature laser ablation. The absolute yield was found to be 1-2 order high than the value extrapolated from the yield at high-temperatures. Polyyne formation by H-capping reaction of the chain-form carbon clusters. The solution obtained under the condition that the fullerenes and polyynes coexist did not contain detectable amount of ring-form carbon clusters.
