The present investigations concern the mixed aggregation of anionic surfactant sodium dodecyl sulfate (SDS) and aminomethylated calix[4]resorcinol (ACR) with ethylsulfonate groups on the lower rim. The interaction between these compounds was investigated by DOSY NMR, tensiometry, conductometry, dynamic and electrophoretic light scattering, atomic force microscopy and drug solubilization. The mixed supramolecular systems based on ACR and SDS can be derived due to pH-switchable properties. Supramolecular assembly took place in acidic medium which caused protonation of the amine groups of ACR and thereby the interaction of charged species in solution. Remarkably, the globular SDS micelles were observed to transform into rod-like micelles in the presence of ACR at lower pH, which can be used to encapsulate the hydrophobic guest molecules.

目前的研究涉及阴离子表面活性剂十二烷基硫酸钠（SDS）和氨基甲基化的杯[4]间苯二酚（ACR）在下部边缘带有乙基磺酸盐基团的混合聚集。通过DOSY NMR，张力测定，电导测定，动态和电泳光散射，原子力显微镜和药物溶解研究了这些化合物之间的相互作用。由于pH可切换的特性，可以得出基于ACR和SDS的混合超分子系统。超分子组装发生在酸性介质中，该介质引起ACR胺基的质子化，从而引起溶液中带电物质的相互作用。值得注意的是，在较低pH下存在ACR时，可以观察到球状SDS胶束转化为棒状胶束，可用于封装疏水性客体分子。
