Abstract Despite recent advances in cluster‐based catalysis for organic synthesis, the substrate scope of reactions catalyzed by metal nanoclusters is typically not superior to previously established catalytic systems. Herein, we develop new atomically precise copper protosilylation, with expanding alkenes and simple enynes that were suitable prior synthetic methodologies traditional complexes. The involvement a second center kernel during migratory insertion step thought be responsible expanded scope. In addition, reaction highly compatible water can carried out open air rather than under inert gas protection. Mechanistic studies suggest cluster‐catalyzed protosilylation proceeds absence silyl radicals. current findings demonstrate potential using practical sustainable chemical synthesis.

Abstract The modulation of traps has found attractive attention to optimize the performance luminescent materials, while understanding trap-involved photoluminescence management metal nanoclusters greatly lags behind, thus extensively impeding their increasing acceptance as promising chromophores. Here, we report an efficient passivation structural oxygen vacancies in AuAg by leveraging H 2 O molecules, achieving a sensitive color tuning from 536 480 nm and remarkably boosting quantum yield 5.3% (trap-state emission) 91.6% (native-state emission). In detail, favored electron transfer relevant contributes weak trap-state emission, which is capable being restrained molecules taking Au-O Ag-O bonds. This scenario allows dominated native-state emission with faster radiative rate. parallel, can rigidify landscape on hydrogen bonding, enabling suppression electron-optical phonon coupling decelerated non-radiative presented study deepens tailoring properties manipulating surface trap chemistry relaxation dynamics, would shed new light customizable performance.

In this paper we present the investigation of reactivity [Rh7(CO)16]3- with InCl3, aim expanding more general study that allowed us to obtain, among other species, icosahedral [Rh12E(CO)27]n- (n = 4 when E Ge or Sn; n 3 Sb Bi) family clusters. Indeed, resulted in isolation and characterization analogous In-centred [Rh12In(CO)28]3- nanocluster (1), which is isoelectronic isostructural congeners. During course reaction two new namely octahedral [Rh6(CO)15InCl3]2- (2) dimeric [{Rh6(CO)15InCl2}2]2- (3) have also been identified. The between InCl3 proved be poorly selective; nevertheless, by fine tuning some parameters it was possible drive towards one product other. Alternatively, can selectively prepared reacting either [Rh5(CO)15]- or, less efficiently, [Rh6(CO)15]2- InCl3. As for only isolated carrying out under inert atmosphere, as opposed CO.
