The investigation of bonding interactions between superatoms continues to be a largely unexplored area study. In this study, we present the synthesis and characterization two F2-type superatomic molecules [Au2Ag25(C7H4NOS)13(DPPB)3] [Au9Ag18(C5H4NS)11(DPPM)5]2+ (Au2Ag25 Au9Ag18 for short, respectively). overall structures were confirmed via X-ray crystallography, revealing horizontal expansion biicosahedral Au2Ag21 yielding vertical Au8Ag15 [Au9Ag18(C5H4NS)11(DPPM)5]2+. Furthermore, their electronic elucidated through density functional theory (DFT) calculations. Spectroscopic analysis absorption characteristics, in conjunction with Tamm–Dancoff approximation DFT (TDA-DFT) calculations, revealed that Au2Ag21(+9) Au8Ag15(+9) cores analogues F2 molecule configuration.

Abstract Surface ligands crucially influence the structure and luminescence of metal nanoclusters (NCs). In this study, three [Ag 25 (SPhCl) 16−x Cl x (DPPB) 6 ] 2+ (x = 0 for Ag , 1 ‐Cl, 4 ‐4Cl) featuring thiol ligand combinations are synthesized investigated. ‐4Cl, which has smallest number rigid ligands, exhibits strongest photoluminescence (PL) chemiluminescence (CL), its PL quantum yield is 73.43% higher than that . Structural analysis indicates being smaller less sterically hindering thiols, compress motif layer towards core, reducing non‐radiative transitions boosting radiative ones to enhance PL. All NCs exhibit CL in presence singlet oxygen, demonstrating ability react with radicals scavenge them. radical scavenging experiments show ‐4Cl highest lowest reaction ability, indicating intensity an NC depends more on intrinsic radicals. The regulation by radical‐scavenging behavior expected be extended other systems related applications.

Abstract Atomically precise copper nanoclusters with crystallization‐induced emission enhancement (CIEE) have garnered significant academic interests‐ but the rational design of high‐nuclearity Cu nanoaggregates atomic structures and CIEE effect remains a long‐standing challenge. Herein, new atomically nanocluster co‐protected by thiolate, phosphine, S 2− ligands, formulated as 34 6 (PFBT) 22 (PPh 3 ) ( , PFBT = pentafluorobenzenethiol, PPh triphenylphosphine), is reported, which possesses typical 12 core P shell. Under photoexcitation at 505 nm, exhibits strong red‐light photoluminescence quantum yield 4.1%. DFT calculations confirm that stems from ligand‐to‐metal charge transfer (LMCT) transition. This nanoaggregate shows effect, crystalline form exhibiting an 800‐fold in intensity compared to its solution form. An in‐depth structural investigation ligand shell reveals extensive C−H···F, C−H···π, π···π interactions significantly restrict intra‐ inter‐molecular rotations vibrations, accounting for phenomena. The red can be selectively quenched CH CN, lower detection limit 9.36 µM (0.38 ppm). study advances development holds potential applications sensing volatile organic compounds (VOCs).
