Glowing gold rings: solvoluminescence from planar trigold(I) complexes

Highly Luminescent Gold(I)–Silver(I) and Gold(I)–Copper(I) Chalcogenide Clusters

“…[9][10][11][12] Gold(I) complexes have received considerable attention recently because they exhibit unique features, such as the formation of secondary bonds through aurophilic interactions [13,14] that are similar in strength to hydrogen bonds. These attractions between closed-shell atoms result from electronic correlation effects strengthened by the large relativistic effects of gold.…”

Luminescence color switching of supramolecular assemblies of discrete molecular decanuclear gold(I) sulfido complexes

“…In a certain sense, they bear an analogy or resemblance to the interesting classes of metal nanoparticles (NPs) (60)(61)(62)(63)(64)(65)(66)(67)(68)(69) and quantum dots (QDs) (70)(71)(72)(73)(74)(75)(76) in that the properties of the nanostructured materials also show a strong dependence on their sizes and shapes. Interestingly, while the optical and spectroscopic properties of metal NPs and QDs show a strong dependence on the interparticle distances, those of polynuclear gold(I) complexes are known to mainly depend on the nuclearity and the internuclear separations of gold(I) centers within the individual molecular complexes or clusters, with influence of the intermolecular interactions between discrete polynuclear molecular complexes relatively less explored (34)(35)(36)(37)(38), and those of polynuclear gold(I) clusters not reported. Moreover, while studies on polynuclear gold(I) complexes or clusters are known , less is explored of their hierarchical assembly and nanostructures as well as the influence of intercluster aggregation on the optical properties (34)(35)(36)(37)(38).…”

While directed supramolecular assembly of discrete Au 12 (52), Au 16 (53), Au 18 (51), and Au 36 (54) metallomacrocycles as well as trinuclear gold (I) columnar stacks (34)(35)(36)(37)(38) have been reported, there have been no corresponding studies on the supramolecular hierarchical assembly of polynuclear gold(I) chalcogenido clusters.…”

Recent advances in the chemistry of gold(I) complexes with C-, N- and S-donor ligands part I: alkynyl, amino, imino and nitrido derivatives

“…In general, the usual linear coordination of goldll) makes its complexes potentially useful metal-based liquid crystalline materials (metallomesogens) (29). In some cases, a relationship between the aurophilic interaction and potentially interesting properties has been suggested, as in the case of the solvoluminescence of some trinuclear complexes (30,31) and luminescence of some alkynyl or alkynyl-isocyanidegold(I) complexes (32,33). Some alkynylgold(I) complexes show non-linear optical properties (34,35) and isonitrilegold(I) nitrates are effective precursors for chemical deposition of gold on iron oxide to give catalysts which efficiently oxidize carbon monoxide in air at low temperatures (36).…”
