Fig. 1: Hierarchical assembly based on Ag9 PBBs.

From: Hierarchical assembly of Ag40 nanowheel ranging from building blocks to diverse superstructure regulation

Fig. 1

a Ag9 building block, protected by two types of thiol ligands. b Monomer Ag11, blocked by two AgNO3 molecules at both ends, inhibited further aggregation. c One-dimensional aggregate {Ag10}n, where Ag9 PBBs are connected by Ag+ ions to form an infinite structure. d Tetramer Ag40 nanowheel, in which four PBBs are gathered together through the silver nodes to form a discrete structure. e One-dimensional aggregate {Ag41}n, in which Ag40 nanowheels are connected by additional Ag atoms to form an infinite structure. Color codes: Ag green, S yellow, C gray, N blue, F cyan, O red. All hydrogen atoms are omitted for clarity.
