Formation of a Linear Supramolecular Polymer by Self-Assembly of Two Homoditopic Monomers Based on the Bis(<i>m</i>-phenylene)-32-crown-10/Paraquat Recognition Motif

Abstract

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.
