Layer-by-layer assembled film can serve as an enhanced reaction environment for Diels-Alder reaction.

ABSTRACT: Although the Diels-Alder reaction (DA) has garnered significant attention due to its numerous advantages, its long reaction time is a drawback. Herein, we investigated the effects of polarity difference on DA using Layer-by-Layer (LbL) films comprising polycationic polyallylamine hydrochloride and polyanionic poly (styrenesulfonic acid-co-furfuryl methacrylate) [poly (SS-co-FMA)] as the reaction environment. First, furan composition in poly (SS-co-FMA) was adjusted to be 19 mol% to achieve good water solubility and layer deposition. The successful formation of LbL films with 8 and 40 layers was confirmed by quartz crystal microbalance. The polarity within films and, consequently, the DA efficiency between furfuryl methacrylate and the maleimide in MAL-PEG₂-NHS incr
