摘要
本文首次利用激光脱附Ｃ（６０）烃基加合物，发现在负离子通道中碳笼不同寻常的碎裂和生长现象。我们详细分析了其形成机理，认为以价键与Ｃ_（６０）结合的自由基起着很重要的作用．这同样亦开辟了打开碳笼及合成巨富勒烯的一种途径．
Abstract We firstly observed the phenomena of fragmentahon and aggregation of fullerenes in laser dcsorption mass spectrometric investigation or radical derivatives of C60 in the negative ion channel. The formation mechanism was mainly attributed to the unique features of the radicals ruptured from the C60 cage, and this may open a new way to synthesize giant fullerenes.
