A phosphonated-functionalized copillar[5]arene was designed and synthesized. H-1 NMR, C-13 NMR, ESI-MS and HR-MS were performed to provide converging evidences of the structure of obtained copillar [5]arene. Driven by hydrophobic interactions and C-H center dot center dot center dot pi interactions between the decyl moiety and the pillar[5]arene cavity, a pH-responsive linear supramolecular polymer was fabricated from this phosphonate-functionalized AB type monomer in water. Concentration-dependent H-1 NMR, NOESY, DOSY, and specific viscometry were carried out to study the supramolecular polymerization process.
