| 摘 要： | 用飞行时间质谱测量３０８ｎｍ激光熔蚀Ｃ６０化学修饰的聚乙烯咔唑（Ｃ６０－ＰＶＫ）与Ｃ６０／聚乙烯咔唑共混物（Ｃ６０／ＰＶＫ）的产物分布，分析了正负离子质谱，发现明显的碳笼融合现象。比较分析了融合过程的增强机理，认为Ｃ６０与ＰＶＫ间的化学键合以及电荷转移络合分别在Ｃ６０－ＰＶＫ键合物和Ｃ６０／ＰＶＫ共混物的富勒烯融合过程中起了重要作用。

| Abstract: | The photoaggregation dynamics of chemically bonded C 60 PVK and C 60 /PVK mixture was studied by laser ablation TOF mass spectrometry. The enhancement of coalescence of fullerene cages in chemically bonded C 60 PVK and C 60 /PVK charge transfer complex was observed. The results indicated that the bonds between PVK chain and fullerene cages are easily broken under laser interaction and the fullerene cages ruptured from the chain are in active excited states favorable to the clustering of the cages. The coalescence behavior of the C 60 /PVK mixture may be caused by the charge tranfer between fullerenes and PVK. |
