摘要
在激光辐照下，Ｃ６０与甲苯反应形成了一系列的富勒烯衍生物，对其中的可溶产物进行的高效液相色谱－质谱－紫外光谱（ＨＰＬＣ－ＭＳ－ＵＶ）分析研究表明，反应产物中包括Ｃ６０（Ｃ７Ｈ７）ｎ，Ｃ６０Ｈｎ，Ｃ６０（Ｃ７Ｈ７）ｎＯｍ等，它们的形成可能与甲苯在激光作用下形成的自由基有关，多级质谱（ＭＳ／ＭＳ）分析表明，这些衍生物是自由基链结在笼状Ｃ６０外围的结果。
A series of fullerene derivatives would be produced by the laser induced reaction of C60 with toluene. High performance liquid chromatography combined with mass spectrometry and ultraviolet spectrometry (HPLC - MS - UV) was developed for separation and characterization of the reaction products, comprising C60(C7H7 )n, C60Hn and C60(C7 H7 )nOm. The derivation might be related to the radical intermediates from laser reaction of toluene. Tandem mass spectra(MS/MS) revealed that the intermediates were bonded at the rim of C60 to form derivatives)
