Synthesis, characterization and coordination behavior of zinc supramolecular polyurethane end-capped with terpyridine

Abstract

A new supramolecular polymer with isocyanate end-groups was synthesized by polymerization of coordination-type monomer (1), with excess bis(4-isocyanatophenyl)methane (MDI). This polymer was then end capped with terpyridine which can be more polymerized in treating with metal ions. The synthesized monomer and polymer were characterized with FT-IR, 1H-NMR and CHNS analysis. The physical properties of the polymer, including viscosity and solubility, were also examined. The coordination behavior of polymer was investigated by using Fe(II) and monitored by UV-Vis spectroscopy and viscometery to show the increasing in the length of the polymer backbone by addition of metal ions. © 2010 Koninklijke Brill NV, Leiden.
