Abstract

ABSTRACT Supramolecular amphiphiles are a topic of widespread interest in supramolecular chemistry and the characterisation of their properties at the interfacesis at the basis of industrial and biotechnology applications. This work focuses on the determination of the adsorption features of supramolecular amphiphiles, formed by the host-guest complexation of a p-sulfonatocalix[4]arene with selected cationic surfactants, at the solid–liquid interface monitored by quartz crystal microbalance with dissipation monitoring (QCM-D) experiments. The adsorption process resulted to be favourite and strongly affected by the length of the surfactant alkyl chain and somehow by the nature of the polar head. The adsorption isotherms highlighted the key role played by the calixarene scaffold in the CMC value, the amount of material absorbed and the efficiency of the adsorption process on a gold substrate. Furthermore, the kinetic profiles provided significant insights on the different mechanisms of adsorption undergone by either conventional or supramolecular amphiphilic systems. Graphical abstract

QCM-D监测杯芳烃类超亲两性试剂在固液界面的吸附

超分子两亲体是超分子化学及其在工业和生物技术应用基础上的界面特性表征的广泛关注的话题。通过石英晶体微平衡耗散监测(QCM-D)实验，研究了超分子两亲体在固液界面上的吸附特性。两亲体是由对磺环[4]芳烃与选定的阳离子表面活性剂的主客体络合形成的。结果表明，表面活性剂烷基链的长度和极性头的性质对吸附过程有很大的影响。吸附等温线显示了杯芳烃支架在CMC值、吸附量和吸附效率方面的关键作用。此外，动力学剖面对传统和超分子两亲体系的不同吸附机制提供了重要的见解。图形抽象

期刊介绍： Supramolecular Chemistry welcomes manuscripts from the fields and sub-disciplines related to supramolecular chemistry and non-covalent interactions. From host-guest chemistry, self-assembly and systems chemistry, through materials chemistry and biochemical systems, we interpret supramolecular chemistry in the broadest possible sense. Interdisciplinary manuscripts are particularly encouraged. Manuscript types include: high priority communications; full papers; reviews, and; Methods papers, techniques tutorials highlighting procedures and technologies that are important to the field. We aim to publish papers in a timely fashion and as soon as a paper has been accepted and typeset it will be published in electronic form on the Latest articles section of the website. The two most important review criteria are that the paper presents high-quality work that fits generally into the broad spectrum of activities in the supramolecular chemistry field. Under normal circumstances, Supramolecular Chemistry does not consider manuscripts that would be more suitable in a highly specialized journal. This includes, but is not limited to, those based mostly or exclusively on topics such as solid state/X-ray structures, computational chemistry, or electrochemistry. . The two most important review criteria are that the paper presents high-quality work that fits generally into the broad spectrum of activities in the supramolecular chemistry field.
