| 摘 要： | 单壁碳纳米管(SWNT)在苯胺中回流，产生碳钠米管-苯胺电荷转移配合物(CNT-AN CTC)．在丙酮稀释液中，用516nm光激发，产生两个荧光发射峰，分别位于564nm和606nm．详细考察了不同胺类化合物对CNT-AN CTC荧光的猝灭作用，结果显示胺所连烷基种类、烷基数目、胺基数目不同对CNT-AN CTC荧光猝灭程度不同，同时探讨了其猝灭机理．

| Abstract: | Under refluxing,carbon nanotube(CNT)and aniline(AN) can form the charge transfer complex (CTC) of CNT-AN CTC.The corresponding fluorescence emission peaks lied at 564nm and 606nm, respectively, with the excitation wavelength of 516nm in the acetone solution. The quenching effects of various amines on CNT-AN CTC fluorescence were investigated in detail. The experimental results showed that amines, with different alkyl, alkyl group numbers as well as amino group numbers, had distinct effects on the CTC fluorescence. In addition ,the quenching mechanism was also discussed. |
