Abstract

Direct methylation of [60]fullerene via a gas-phase reaction in a CH4/H2 atmosphere was performed using a modified hot filament chemical vapor deposition method. Pressures were varied from 10 to 60 mbar and the substrate was maintained at 690 degrees C. High-resolution matrix-assisted laser desorption ionization (MALDI) mass spectrometry analysis showed signals corresponding to C60H18-2n(H,CH3)n. Collision-induced dissociation experiments confirmed a maximum of 18 ligands possible to the [60]fullerene cage.

摘要

采用改进的热丝化学气相沉积法，在CH4/H2气氛中通过气相反应对[60]富勒烯进行直接甲基化。压力在10至60毫巴之间变化，底物保持在690摄氏度。高分辨率基质辅助激光解吸电离（MALDI）质谱分析显示出对应于C60H18 - 2n(H,CH3)n的信号。碰撞诱导解离实验证实，[60]富勒烯笼最多可连接18个配体。
