Heterometal doping of metal nanoclusters is a powerful method for tuning their physicochemical properties. Thus far, the dopants incorporated into are limited to group 10–12 metals with closed d-shells. In Research Article (e202302591), Eunji Sim, Dongil Lee, and co-workers show that open d-shell 8 9 can be silver nanocluster by forming metal-hydride superatoms.

Abstract A polyhydrido copper nanocluster, [Cu 14 H 10 (PPh 3 ) 8 (SR) ] + (HSR = 2,4-dimethylbenzenethiol), adopting a distorted fcc structure, is reported. One cube-vertex atom, coordinated by the three thiolate ligands and PPh , protrudes outwards from metal framework. The twisting of about threefold axis lowers symmetry O h (Cu to C forming racemic pairs intrinsic chiral clusters in crystal...

Organic-inorganic hybrid molecular architectures utilizing self-assembled monolayers (SAMs) of organic chromophores (e.g., acene derivatives) are systematically discussed to examine the photophysical properties together with covalently-linked dimeric and oligomeric forms. Multi-exciton generation (i.e., singlet fission) light energy conversion processes that occur in a reaction site composed ch...

X-Ray Detection and Shielding In article number 2206782, Jian-Qiang Wang, Jian Lin, co-workers demonstrate a bifunctional platform for X-ray detection shielding, which is realized by stepwise crystallization of millimeter-scale thorium cluster single crystals. The judicious synergy between high-Z cations 3-(pyridin-4-yl)benzoate ligands gives rise to radiochromic nanocluster, whose attenuation ...

Langmuir–Blodgett technique is utilized to deposit ultrathin films of Au38(SC2H4Ph)24 nanocluster onto solid surfaces such as mica and silicon. The morphologies the transferred at various surface pressures within mono/bi/trilayer regime are studied by atomic force microscopy (AFM). time spent on water before deposition has a decisive effect final ordering nanoclusters network fast AFM, X-ray re...
