Reversible organic reactions have been studied in various applications including self-healing coatings, self-healing soft robotic actuators, drug delivery system and so on. The retro-Diels-Alder reaction, the microscopic reverse of the corresponding Diels-Alder reaction, attracts much attention due to its facile accomplishment with heat. In this study, the reversible Diels-Alder reaction of a furan compound with a bismaleimide compound was investigated. Reaction conditions to control the direction of the Diels-Alder reaction, forward or backward, were optimized. Polyurethanes possessing a furan moiety was prepared, and the crosslinking and retro-crosslinking process using a bismaleimide linker was investigated. Storage and release of small particles by the reversible process is currently under study.
