中文摘要 | 碳六十有機溶液於照光下,產生三重態碳六十,兩個三重態碳六十會進行自身氧 化還原反應而生成 C �� + C �� - 正負離子自由基,C �� + 及 C �� - 離子自由基的生成 可合理解釋文獻上所報導諸多碳六十光化學、物理性質,如非線性光學性質、光激發高分子 化、及三重態碳六十生命期隨雷射光強度變化等現象。 ESR 光譜研究亦顯示,C �� + 會與 溶劑 (如,甲苯、苯甲氰 ) 及親核試劑 (如:水、甲醇 ) 進行加成反應。而 C �� - 則極 易與 O �祐@用生成 C �� O �� -,C �� O �� - 有二種結構異構物, 在文獻上以往一直被 錯誤指認為 C ���� - 或自由態 C �� - 自由基。 |
英文摘要 | Triplet C��(�饅��) was formed by irradiation of C��-organic solvent system. Two �� C �� were found to undergo disproportionation.and generate C �� + as well as C �� - ion radicals. The formation of C �� + and C �� -. ion radicals can rationalize various photophysical and photochemical properties of C �� as reported in literature, scuh as, nonlinear optical property, photoinduced polymerization of C �� solid thin film, and laser light intensity dependence of �� C �� lifetime, etc. ESR studies reveal that C �� + cation radical can react with solvent molecules (e.g., toluene and benzonitrile) and nucleophiles (e.g., H �� O and methanol). C �� - anion radical reacts with O �� to form C �� O �� -. C �� O �� - has two interconvertable structual isomers, which were often misassigned inliterature as C ���� - dianion (radical) or free C �� - radical. |
