In the search for novel polymeric molecules that could be used as electroactive materials, seven polyenaminones were prepared in high yields by transaminative polymerization of resorcinol-derived bis-enaminones with m- and p-phenylenediamine 2,5-diaminohydroquinone. The obtained polymers show very low solubility organic solvents absorb UV light visible at wavelengths below 500 nm. All products tested redox activity a Li battery setup. 2,5-diaminohydroquinone-derived compound showed best activity, maximum capacity 86 mAh/g relatively good retention, thus confirming hydroquinone group primary redox-active group. Other potential groups, such resorcinol conjugated carbonyls, limited while variations phenylene groups substitution phenolic residue did not impact electrochemical polymers. Their properties, together their previously established chemical recyclability, make promising scaffolds development materials sustainable energy storage applications.
