[Cu₁₈H₃(S-Adm)₁₂(PPh₃)₄Cl₂]: fusion of Platonic and Johnson solids through a Cu(0) center and its photophysical properties

Abstract

Structural elucidation of the atom-precise thiolate-protected copper nanoclusters (Cu NCs) containing Cu(0) is quite challenging. Here, we report a new adamantane thiol protected [Cu18H3(S-Adm)12(PPh3)4Cl2] (Cu18) NC which reveals the first...

Switchable catalysis and CO2 sensing by reduction resistant, luminescent copper–thiolate complexes

“…Such properties can be explored in developing various sensors. [25][26][27][28][29][30][31] For example, copper-cysteine complexes exhibits have been used as a qualitative/quantitative sensor for ammonia in solutions. 32,33 Therefore, finding a suitable thiol ligand is important to obtain desirable properties from copper-complexes.…”

Eight-Electron Superatomic Cu31 Nanocluster with Chiral Kernel and NIR-II Emission

“…A major reason for this is believed to be the much lower M(I)/M(0) half-cell reduction potential of copper (0.52 V) than those of silver (0.80 V) and gold (1.69 V), which makes the Cu(0)-containing clusters air-sensitive and challenging to achieve. 30,31 To date, only a handful of such copper nanoclusters (Cu 13 , 32 Cu 14 , 33 Cu 18 , 34 Cu 20 , 35 Cu 23 , 36 Cu 25 , 31 Cu 29 , 37 Cu 53 , 38,39 and Cu 61 40 ) have been documented, precluding their comprehensive studies. Except for [Cu 53 (C� C P h P h ) 9 ( d p p p ) 6 C l 3 ( N O 3 ) 9 ] ( d p p p = 1 , 3 -b i s -(diphenyphosphino)propane), 38 all of the previously reported copper nanoclusters contain less than five free electrons, while gold and silver nanoclusters bearing eight or more free electrons are conspicuously more prevalent.…”

Unusual core engineering on a copper hydride nanoball

“…3 A series of ligand-stabilized copper hydride clusters with various hydride coordination modes, including capping, bridging, and interstitial, have been reported. 3,4 Using single-crystal neutron diffraction techniques, the positions of high nuclearity copper hydrides stabilized by dichalcogenolates have been reliably determined. Notable examples are Cu 7 H and Cu 28 H 15 ligated by dithiocarbamate (dtc), 5,6 Cu 20 H 11 , 7 Cu 30 H 18 .…”
