Facile synthesis of the chemically oxidative grafted copolymer of 2,6-diaminopyridine (DAP) and thiophene (Th) for optoelectronic and antioxidant studies

Synthesis of poly(2,6-diaminopyridine) using a rotating packed bed toward efficient production of polypyrrole-derived electrocatalysts

“…The final product showed two discernible bands at ∼240 nm and ∼320 nm, which correspond to the π → π* transition of pyridine rings. 37 Compared with the DAP monomer, the increased wavenumber of the second peak after the reaction indicates a polyconjugated bond structure of the product and it is more electrically conductive than its monomer. 38 Moreover, a more detailed polymerization investigation was carried out based on HPLC results.…”
