(R)evolutionary energy-storage density: Dewar pyrimidones inspired by nature
Other text in scientific journal, 2026

In Science , Han and co-workers establish pyrimidone derivatives and their Dewar photoisomers as a new class of photoswitches for molecular solar thermal energy storage (MOST). The photoswitches exhibit record-high energy densities up to 1.65 MJ/kg and release sufficient heat to boil water within 1 s, moving MOST toward concrete applications.
