One of the most recently explored materials at the nanoscale includes atomically precise clusters, which exhibit diverse chemical reactions.1-3 The study of their science encompasses various aspects such as kinetics and thermodynamics, currently undergoing intensive exploration.4 Although alloy clusters synthesized by Intercluster reactions possess certain common structural features, they exhibit distinctly different reactivities in their substitution reactions.5 New insights from this science will further enrich the area of nanoscale materials. The availability of ligand protected clusters with precisely known structures opened the possibility to explore their chemistry in greater detail. Our group previously discovered interparticle reactions in the solution phase involving atomically precise noble metal clusters, resembling reactions between molecules.6 These reactions demonstrate that the nature of the metal−thiolate interface, including its bonding network and dynamics, plays crucial roles in dictating the type of exchange processes and overall rates. This spontaneous process is driven by the entropy of mixing and involves events at multiple time scales. This underscores the potential to enhance our understanding of nanoscale reaction mechanisms by delving deeper into cluster reactions. In this study, we conducted reactions between centre-doped [MAg24(DMBT)18]- and [MAg28(BDT)12]3- (M= Ag, Au, Pd, and Pt) nanoclusters. The aim was to gain further insights into the reactivity of different central atom-doped Ag25 clusters. In this research proposal seminar, a thorough literature review on mass spectrometric studies on nanoclusters will be discussed and a future perspective will be given.
