An amphiphilic pillar[5]arene was made. It could self-assemble to form vesicles and multiwalled microtubes in water. Dynamic light scattering, transmission electron microscopy, scanning electron microscopy, atomic force microscopy, and UV-vis and FTIR spectroscopy were employed to characterize its self-assembly process and the resultant assemblies. The vesicles could encapsulate calcein within their interiors under neutral conditions and release it in response to a decrease in pH. The microtubes, which have primary amine groups on their surfaces, could adsorb TNT through donor-acceptor interactions.

A pillar[5]arene prepared from monomer 1 has four constitutional isomers. Although these constitutional isomers have the same molecular formula, their other properties that we have investigated are more or less different. They have different melting points, different NMR spectra and different crystal structures. Furthermore, the corresponding four anionic constitutional pillar[5]arene isomers derived from these four constitutional isomers showed different binding abilities with paraquat G in water. The association constants of 3a?G, 3b?G, 3c?G and 3d?G were determined to be (3.33±0.46)×104 L·mol-1, (5.00±0.63)×104 L·mol-1, (3.33±0.28)×104 L·mol-1, and (1.43±0.09)×104 L·mol-1, respectively.
