Heteracalixaromatics are an emerging generation of macrocyclic host molecules in supramolecular chemistry. As a typical example of heteracalixaromatics, oxacalix[2]arene[2]triazine adopts a shape-persistent 1,3-alternate conformation and can be easily functionalized. Taking it as a platform, a series of oxacalix[2]arene[2]triazine-based amphiphiles bearing long alkyl chains were synthesized through post-macrocyclization functionalization or 3+1 fragment coupling protocols. The self-assembly behavior of these amphiphiles in a mixture of tetrahydrofuran(THF) and water was investigated. Dynamic light scattering(DLS)measurements revealed that the size of the self-assembled aggregates is dependent on the structure of the amphiphiles. The long alkyl chain substituents and/or intermolecular hydrogen bonds were found to promote the self-assembly.
