用荧光光谱法研究了多环芳烃（PAHs）与单壁碳纳米管（SWNTs）的相互作用。作为浓度的函数的荧光猝灭建模，揭示了相互作用导致的碳纳米管的解开的区域。由该模型计算了多环芳烃与单壁碳纳米管的结合能。结果表明，多环芳烃与单壁碳纳米管的结合能与多环芳烃的分子量呈线性关系。通过绘制这些值的结合能对这些多环芳烃的分子量，一个良好的结构-性能的相互作用关系已被证明。
The interaction between polycyclic aromatic hydrocarbons (PAHs) and single walled carbon nanotubes (SWNTs) has been studied by fluorescence spectroscopy. Fluorescence quenching as a function of concentration is modeled, revealing regions where the interaction causes a debundling of the carbon nanotubes. The binding energies between PAHs and SWNTs are obtained from the model. It is found that there is a linear correlation between the binding energy of PAHs with SWNTs and the molecular weight of the PAHs. By plotting these values of binding energy against the molecular weight of these PAHs, a good structure-property relationship governing the interaction has been demonstrated.
