In this study, we examine the use of charge-transfer interactions between polycyclic aromatic hydrocarbons (PAHs) and planar organic cations in nonaqueous capillary electrophoresis. Since the separations are performed in a purely nonaqueous medium, this method also facilitates the analysis of solutes that have low solubilities in aqueous or mixed media. Presented in this study are the separations of PAHs as well as the quantitative structure-migration relationships that assisted in achieving a better understanding of the forces through which the PAH molecules interact with the acceptor cation. It was found that, in addition to charge-transfer interactions, electrostatic and dispersive forces play an important role in PAH-cation binding.
在本研究中，我们考察了多环芳烃（PAHs）与平面有机阳离子之间的电荷转移相互作用在非水毛细管电泳中的应用。由于分离是在纯非水介质中进行的，该方法也便于分析在水相或混合介质中溶解度较低的溶质。本研究展示了多环芳烃的分离以及定量结构-迁移关系，这些关系有助于更好地理解多环芳烃分子与受体阳离子相互作用的作用力。研究发现，除了电荷转移相互作用外，静电和色散力在多环芳烃-阳离子结合中也起着重要作用。
