Synthesis of Novel (bis‐)1,5‐Disubstituted‐1H‐tetrazole‐Decorated Monomers and Their Respective Polymers via Thiol‐ene Polymerization.

Over the years, nitrogen‐rich functional groups like tetrazole and its derivatives have received increasing interest in the chemistry of small molecules. There is a continuously growing interest in polymers decorated with nitrogen for potential biomedical applications because of their broad range of biological properties, such as being antibacterial, anticarcinogenic, and anti‐inflammatory. On this premise, a new synthesis route is reported for nitrogen‐decorated polymers via the combination of Ugi‐azide four‐multicomponent reaction (UA‐4MCR) and thiol‐ene polymerization. Accordingly, α,ω‐diene monomers decorated with (bis‐)1,5‐disubstituted‐1H‐tetrazoles (bis‐1,5‐DS‐Ts) are synthesized by using the UA‐4MCR. Subsequently, the light‐induced thiol‐ene polymerization facilitates the efficient synthesis of novel tetrazole‐decorated polymers with apparent number average molecular mass (Mn) up to 62 000 g mol−1, which are characterized for their chemical, thermal, and optical properties. The comprehensive characterization of the synthesized polymers is paving the way toward a wealth of opportunities, ranging from biomaterials to energy storage−relevant materials.
