“…The advancement of organic synthesis techniques has had a significant influence on the design and synthesis of innovative structures incorporating spirocyclic, polycyclic, and heterocyclic groups. − The importance of these groups in the field of polymer chemistry has also arisen as an exceptionally promising domain due to the desirable qualities of them, such as enhanced mechanical strength, thermal stability, and electrical conductivity. − One particular class of the heterocyclic compounds, known as tetrazoles, specifically nitrogenous heterocyclic 1,5-disubstituted-1 H -tetrazoles (1,5-DS-Ts), has been gaining significant attention due to its effectiveness in applications such as energy systems, − nanomaterials, − metal–organic frameworks, and medicinal compounds. , Despite the existence of diverse and complex libraries of 1,5-DS-Ts as small compounds, − integrating them into polymer chemistry remains a challenging issue to be addressed. Indeed, it has been observed that the majority of currently available 1,5-DS-T containing polymers are predominantly composed of a carbon–carbon backbone with tetrazole side chains, rather than the main chain .…”
