〈div〉〈p〉Novel oligo- and polyenaminones with 〈em〉M〈/em〉〈sub〉〈em〉w〈/em〉〈/sub〉 ∼ 3000 Da were prepared in excellent yields by amino–enaminone ‘click’ polymerisation of 1,3- and 1,4-bis[3-(dimethylamino)acryloyl]arenes with 1,3- and 1,4-phenylenediamine. The obtained oligomers and polymers were depolymerised quantitatively to the starting bis-enaminones and diamines by treatment with excess dimethylamine in ethanol at 50 °C. This simple polymerisation/depolymerisation method allows for a closed-loop recycling of polyenaminone-based materials. UV light absorbance at wavelengths below 470 nm indicates promising optical properties of these polymers.〈/p〉〈/div〉
