Formation of a linear supramolecular polymer by self-assembly of two homoditopic monomers based on the bis(m-phenylene)-32-crown-10/Paraquat recognition motif

A homoditopic monomer containing two bis(m-phenylene)-32-crown-10 units and a complementary homoditopic monomer containing two paraquat moieties were designed and prepared. At high equimolar concentrations (> 40 mM) they self-organize to form a linear supramolecular polymer in solution as confirmed by proton NMR spectroscopy, mass spectrometry, and viscosity studies.
