Pyridine and its derivates are aromatic bases that are widely used in various applications. However, due to their great solubility in water and many organic solvents, they are
hard to separate and recycle. Thus, incorporation of pyridine moieties into polymers is of considerable interest to increase their recyclability.
Herein, we present a new approach that incorporates the pyridine moiety directly into the polymer backbone. Monomers were prepared using the Hantzsch dihydropyridine
synthesis with subsequent oxidation. For the Hantzsch reaction, only renewable starting materials were used. Oxidation of the Hantzsch dihydropyridines was performed
using potassium peroxydisulfate, which is fully recyclable by electrolysis. For polymerization of the prepared monomers, two different approaches were investigated: acyclic
diene metathesis and polycondensation.
