“…Historically, mass spectrometry-based analysis of gold cluster compounds has lagged behind other methods such as X-ray crystallography due to traditional ionisation methods such as electron ionisation or chemical ionisation being incompatible with compounds of low volatility. It appears that the first analytical studies of gold cluster compounds had to wait until the advent of fast atom bombardment (FAB) [54], which allowed transfer of gold cluster cations such as [Au 6 (PPh 3 ) 6 ] 2+ to the gas phase [55].…”

With the advent of electrospray ionisation (ESI) and matrix-assisted laser desorption ionisation (MALDI), mass spectrometry (MS) is now routinely used to establish the molecular formulae of gold nanoclusters (AuNCs). ESI-MS has been used to monitor the solution phase growth of AuNCs when gold salts are reduced in the presence of phosphine or thiolate ligands. Beyond this analytical role, over the past 2 decades MS-based methods have been employed to examine the fundamental properties and reactivities of AuNC ions. For example, ion mobility and spectroscopic measurements may be used to assign structures; thermochemical data provides important information on ligand binding energies; unimolecular chemistry can be explored; and ion-molecule reactions with various substrates can be used to probe catalysis by AuNC ions. MS can also be used to monitor and direct the synthesis of AuNC bulk material either by guiding solution phase synthesis conditions or by soft landing a beam of mass-selected (i.e. monodisperse) AuNC ions onto a surface. This review showcases all areas in which mass spectrometry has played a role in AuNC science.
