Synthesis of Azobenzene-Diol Chain Extender-Based AcidochromicPolyurethane

Smart polymers are the next destination for the development of polymer and materials science. Inthis study, smart acidochromic polyurethanes (PUs) were synthesized with N,N-dihydroxyethylazobenzene (AZO) as the chain extender. The chemical structure of the resulting azobenzene andpolyurethanes was confirmed by Fourier transform infrared spectroscopy. The synthesized AZO andPUs showed a distinct coloration in the acidic environments.
