Abstract:
A unique assembly of a two-electron superatom, [Ag10{S2P(OPr)2}8], as a primary building unit in the construction of a supramolecule [Ag10{S2P(OPr)2}8]2(μ-4,4'-bpy) through a 4,4'-bipyridine (4,4'-bpy) linker is reported. This approach is facilitated by an open site in the structure that allows for effective pairing. The assembled structure demonstrates a minimal solvatochromic shift across organic solvents with variable polarities, highlighting the influence of self-assembly on the photophysical properties of silver nanoclusters.
