Nanoparticles functionalized with photoresponsive molecules assemble into supracrystals on irradiation with UV light and disassemble on irradiation with visible light. These dynamic structures can trap small molecules from the surrounding solution and accelerate chemical reactions in repeated cycles. The artist's impression in the cover shows anthracene dimerization inside the supracrystal structure, with reactants going in and products coming out.
