Summary: Self-assembly is a common phenomenon in living systems, and scientists have been trying to emulate its intricacy, homogeneity, and versatility in artificial building blocks. Self-sorting assembly in multicomponent systems allows for the spontaneous recognition and spatial aggregation of the same or interactive building units, leading to well-ordered products or hierarchical structures in a one-step manner. This efficient assembly strategy has attracted significant research attention, particularly in artificial systems using supramolecular and polymeric building blocks.

Summary: The study investigated the size-dependent energy harvesting from nonthermalized, upper excited states of glutathione-protected gold clusters, showing that the upper excited-state energy can be efficiently harvested by an energy acceptor attached to the clusters. This opens up a new avenue for energy harvesting from nonthermalized upper excited states of gold clusters that would otherwise be lost as heat.
