Probing Hydrogen Bonding and Proton Mobility in Dicyanoimidazole Monomers and Polymers

Hydrogen bonding and proton mobility are important features in many polymers. In this work, hydrogen bonding is studied in both monomers and polymers of dicyanoimidazoles using infrared and solid-state NMR spectroscopy and polymer viscosity studies. Hydrogen bonding accounts for an unusual complexity in the nitrogen−hydrogen stretching region of the infrared spectra. The influence of hydrogen bonding on properties was observed in several …
