“…[ 223 ] and Sun et al. [ 224 ] investigated the significance of the position ( ortho or para ) of COOH group on the bound ligands during the self‐assembly of NCs via hydrogen bonding. To address this, (NH 4 ) 9 [Ag 9 ( o ‐MBA) 9 ] and (NH 4 ) 9 [Ag 9 ( p ‐MBA) 9 ] NCs were prepared in water by the pH‐mediated reduction of silver nitrate (AgNO 3 ) in the presence of o ‐MBA or p ‐MBA.…”

“…For example, the self‐assembled nanofibers fabricated from (NH 4 ) 9 [Ag 9 ( o ‐MBA) 9 ] NCs via hydrogen bonding method showed an enhanced AIE together with a transition from fluorescence to phosphorescence owing to their structural rearrangement within nanofibers. [ 223 ] AIE has been further extended to different assembled NCs, including [Au 25 ( p ‐MBA) 18 ] − , [ 262 ] [Au@SG‐PAH], [ 273,318,319 ] [Au 3 {(R or S)‐Tol‐BINAP} 3 Cl], [ 246 ] and (NH 4 ) 9 [Ag 9 ( p ‐MBA) 9 ], [ 224 ] .

Ligand protected noble metal nanoparticles are excellent building blocks for colloidal self‐assembly. Metal nanoparticle self‐assembly offers routes for a wide range of multifunctional nanomaterials with enhanced optoelectronic properties. The emergence of atomically precise monolayer thiol‐protected noble metal nanoclusters has overcome numerous challenges such as uncontrolled aggregation, polydispersity, and directionalities faced in plasmonic nanoparticle self‐assemblies. Because of their well‐defined molecular compositions, enhanced stability, and diverse surface functionalities, nanoclusters offer an excellent platform for developing colloidal superstructures via the self‐assembly driven by surface ligands and metal cores. More importantly, recent reports have also revealed the hierarchical structural complexity of several nanoclusters. In this review, the formulation and periodic self‐assembly of different noble metal nanoclusters are focused upon. Further, self‐assembly induced amplification of physicochemical properties, and their potential applications in molecular recognition, sensing, gas storage, device fabrication, bioimaging, therapeutics, and catalysis are discussed. The topics covered in this review are extensively associated with state‐of‐the‐art achievements in the field of precision noble metal nanoclusters.

A novel ladder-type coordination polymer (CP), poly[(μ-4,4′-bipyridine-κ2 N:N′){μ-4-[(4-carboxybenzyloxy)methyl]benzoato-κO}silver(I)](Ag—Ag), [Ag(C16H13O5)(C10H8N2)] n or [Ag(HL)(4,4′-bpy)] n {H2 L is 4,4′-[oxybis(methylene)]dibenzoic acid and 4,4′-bpy is 4,4′-bipyridine}, was synthesized using hydrothermal methods. The complex was characterized by IR spectroscopy, elemental analysis and single-crystal X-ray diffraction, and is a ladder-type CP which exhibits an obvious Ag—Ag interaction. The legs of the ladder are formed by parallel 4,4′-bipy ligands and silver ions, and the rungs are constructed by Ag—Ag interactions. A Hirshfeld surface analysis was carried out and is discussed in detail. The complex also displays favourable fluorescence properties.
