【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.更多还原
