Switchable photon and phonon emission properties of an atomically precise Ag₁₄core-based two-dimensional silver cluster-assembled material

Abstract

Changes in structural architecture via interlayer C–H⋯F interactions triggered by solvent molecules influence the dual (photon and phonon) emission mechanism of a two-dimensional cluster-assembled material, [Ag14(StBu)10(CF3COO)4(4,4′-azopyridine)2].

An atomically precise silver nanocluster for artificial light-harvesting system through supramolecular functionalization

“…The crystallographic data reveals that the bond distances of Ag I ⋯Ag I in the Ag 16 core fall in the range of 2.95–3.39 Å, which are lower compared to twice the van der Waals radius of Ag (3.44 Å). 50,51 The average distance indicates that some sort of long-range non-covalent interaction (NCI) is present between the two Ag atoms which must be an argentophilic interaction. 52 We have calculated the weak metallophilic interaction such as bond critical point (BCP), bond order, and NCI of two adjacent Ag atoms of the Ag 16 core.…”

Template-assisted alloying of atom-precise silver nanoclusters: a new approach to generate cluster functionality

“…The precursor, AgS t Bu complex was synthesized by treating equimolar amounts of AgNO 3 and HS t Bu with Et 3 N in methanol. 46…”

Silver cluster-assembled materials for label-free DNA detection

“…The structure of Ag 14 bpa SCAM was determined by single-crystal X-ray diffraction (SCXRD) studies that exhibited monoclinic crystal system, space-group type C2 / c (Table S1, ESI†). Similar to the situation in Ag 14 apy, 15 the core of the Ag 14 cluster in Ag 14 bpa adopts the shape of a slightly distorted ortho-bielongated square pyramid (Fig. S1, ESI†) in which the Ag5 atoms are located at the apical sites (Fig.…”

“…7 Since then, the library of SCAMs has expanded by combining the diverse geometry and composition of silver cluster nodes with a wide array of organic linkers. [8][9][10][11][12] The combination of silver clusters and organic linkers has not only endowed the SCAMs with augmented stabilities but also with unprecedented performance such as enhanced photoluminescence quantum yields [13][14][15][16] and superior photocatalytic bacterial inactivation, 17 among others. However, acetylenic bispyridine linkers have not hitherto been reported to construct the SCAMs.…”
