Phase Change Coordination Polymers as Sustainable Memories

Gold thiolate phase change coordination polymers are a sustainable alternative to the inorganic chalcogenides for Phase Change Memories. Indeed, they exhibit reversible solid-state amorphous-to-crystalline transitions under mild conditions of temperature and pressure and display an ON/OFF switch of the luminescence as an efficient optical SET/RESET language. In addition, their structural flexibility allows a molecular precision of the phase change.
