The photoluminescence from functionalized single-walled carbon nanotubes was found to be highly sensitive to the presence of nitroaromatic compounds such as nitrobenzene, 4-nitrotoluene, and 2,4-dinitrotoluene. The strong luminescence quenching in solution was at the upper limit of diffusion-control and also showed significant static quenching contributions. Mechanistic implication of the results and potential applications are discussed.
研究发现，功能化单壁碳纳米管的光致发光对硝基苯、4-硝基甲苯和2,4-二硝基甲苯等硝基芳香化合物的存在高度敏感。溶液中强烈的发光猝灭处于扩散控制的上限，并且还表现出显著的静态猝灭贡献。文中讨论了该结果的机理意义及潜在应用。
