摘要：
A new amphiphilic molecule based on the calix[4]arene scaffold was synthesized by. appending perfluoroalkyl chains on the upper rim and polar groups on the lower rim of the macrocycle. This molecule self-assembles in water and methanol due to formation of a super-hydrophobic fluorous phase. Bilayer assemblies were observed using dynamic light scattering (131,S) and transmission electron microscopy (TEM). The aggregate architecture is strongly influenced by the solvent. Fibers formed by stacked disks were observed in methanol, whereas spherical aggregates were favored in an aqueous environment.
