Bridging between silver clusters and polyoxoanion clusters, the first 1D assembly, [Ag34(StBu)26(W6O21)(CF3COO)](CF3COO)·Et3N·20CH3OH (1), based on POM-templated silver-thiolate nanoclusters featuring a [Ag34(StBu)26(CF3COO)]7+ shell and a [W6O21]6− core is reported. This novel core–shell nanocluster possesses nanoscopic morphology, displays intense deep-blue emission in solution under ambient conditions and also shows special electrochemical properties.
Highest nuclearity M48 (M = CoII or NiII) cage clusters have been constructed by [12+18] condensation of twelve M4-p-tert-butylthiacalix[4]arene second building units (as vertices) and eighteen asymmetric 5-(1H-tetrazol-1-yl)isophthalate ligands (as faces), showing a merohedral icosahedron-type framework.
The first example of 1D self-assembly of carbonate-templated sandwich-like macrocycle-based Ag20S10 nanoclusters, {[(CO32−)@Ag20(StBu)10(CH3COO)8(DMF)2]·2H2O}n (1), is reported. Compound 1 is stable both in the solid state and in solution. It exhibits potential wide gap semiconductor properties, reversible thermochromic luminescence behaviour and excellent electrochemical properties.
The first macrocycle-based high-nuclearity nanocluster [Ag20(StBu)10(CF3COO)2]8+ in complex 1, with a sandwich-like structure constructed by bilevel inversion Ag5S5 pentagrams and an interlayer Ag10 ring, has been obtained. Structure analysis indicates that Cl− acts as an anion template to direct the formation of 1. In addition, the photoluminescent property of complex 1 is also investigated.
A high-nuclearity Cd24 cluster built from Cd 4 -thiacalix[4]arene SBUs and in situ generated peroxyphosphate PO 53− exhibited significant photocatalytic water splitting activity in absence of a co-catalyst.
