Structure-correlated Optical Properties of Monolayer-protected Metal Clusters Studied Through Magneto-optical and Time-resolved Spectroscopies Book Review:

Magneto-optical (MO) and femtosecond time-resolved spectroscopies have been employed to study the electronic structure and relaxation dynamics of atomically precise monolayer-protected clusters (MPCs). To begin, magnetic circular dichroism (MCD) spectroscopy was introduced and employed to characterize the excitation spectrum of the Au102(pMBA)44 and Au25(PET)18 clusters. It is demonstrated through variable-temperature variable-field (VTVH ) MCD analysis of the Au102(pMBA)44 cluster that: a) the optical properties of distinct structural motifs within MPCs are individually spectroscopically addressable; and b) MO spectroscopy provides the quantification of necessary electronic structure parameters to sufficiently characterize these systems. Electronic structure parameters determined through VTVH analysis, of note, are Land g-factors, fine structure splitting energies, and Faraday Term contributions to the optical magnetic response. From VTVH -MCD study of the Au102(pMBA)44 cluster, the long-contended mechanism for previously observed low temperature magnetism in nanoscale gold was addressed.Having demonstrated the usefulness of VTVH -MCD spectroscopy, the emission analogue, magnetic circular photoluminescence (MCPL) spectroscopy was developed. It was shown through study of the Au25(PET)18 cluster that VTVH -MCPL retains the fundamental formalism and information content of VTVH -MCD. The application of these electronic structure parameters to transient dynamics were utilized in determining the state-resolved mechanism for Au25(PET)18 PL. From this PL mechanism, state-resolved carrier relaxation pathways correlated to superatom-based emission and metal-to-ligand charge transfer emission were characterized. Incorporated into the PL mechanism for Au25(PET)18 were spectroscopic term symbols and fine structure splittings as quantified through VTVH -MCPL analysis. A relation between superatom-based emission to plasmon-mediated emission in larger Au systems was proposed. Next, the influence of structural modification of the Au25(PET)18 cluster on the emission-related carrier dynamics was studied through VTVH -MCPL and VT-PL spectroscopy. To begin, the effect of metal doping to the Au25(PET)18 icosahedral core was studied through analysis of the PdAu24(PET)18 cluster. The PdAu24(PET)18 cluster exhibited significantly lower superatom-based emission intensity, and resulting global PL yield, relative to the Au25(PET)18 cluster. Land g-factor determination and electronic-vibrational coupling analyses suggests that the observation of low emission yield was related to strong coupling to nonradiative channels due to emission from high angular momenta states. The increase in angular momenta was related to spin-orbit coupling interactions between the Pd dopant and surrounding Au icosahedron. Next, the carrier dynamics of the Au25(PET)18 cluster were compared to different sized clusters, namely Au20(PET)15 and Au38(SC12H25)24. Cluster-specific, temperature-dependent PL intensity behaviors were related to size-dependent fine structure energies. In particular, the observation of increased PL intensity for the Au20(PET)15 was related to fine structure resonant, vibrationally mediated energy transfer. The final portion of this thesis focuses on understanding electronic coupling dynamics in MPC dimers. Samples of Au20(PET)15 MPC dimers were formed utilizing a n-ethylene glygol dimethyl ether (n-glyme) molecular bridge. Femtosecond time-resolved transient absorption (fsTA) spectroscopy was utilized to probe the excited-state dynamics for Au20(PET)15-n-glyme-Au20(PET)15 dimers. Effective intercluster separation was controlled using variable length n-glyme, where n = di-, tri-, and tetra-, bridging molecules. A separation-dependent dimer-specific carrier relaxation channel was observed with time constants of 130 20, 60 8, and 36 6 ps for the n = di-, tri- and tetra- dimers, respectively. The increased relaxation time has been attributed to intercluster separation-dependent stabilization of dimer-specific relaxation states. This dimer-specific relaxation channel was further investigated using VTVH -MCPL spectroscopy. VTVH analysis of the dimer PL quantified primarily B-term contributions to the differential response indicating strong coupling between degenerate states. This assignment was in agreement with previous VTVH -MCD studies of polynuclear Au(I)-centered complexes. The results implicated coupling between degenerate Au(I) atoms located in the inorganic semiring units of each cluster as the primary source for emergent dimer carrier dynamics.

Small metal clusters exhibit physical and chemical properties that differ substantially from those of corresponding bulk metals. Furthermore, the properties of clusters vary greatly depending on the number of constituent atoms. Metal clusters with these characteristics currently attract great attention in a wide range of fields as new nanoscale functional materials. In recent years, the techniques to precisely synthesize metal clusters protected with organic ligands and polymers with atomic precision have advanced dramatically. In addition, substantial knowledge of the size-specific physical/chemical properties exhibited by these metal clusters has been accumulated. In this chapter, we describe the precise synthesis methods of the most studied thiolate (SR)-protected gold clusters Aun(SR)m and their heteroatom-substituted clusters (alloy clusters).

Metal Nanoparticles and Nanoalloys Book Review:

The field of nanoscience has undergone tremendous growth in the past decade as the number of applications of nanoparticles and nanostructured materials have proliferated. Metal nanoparticles have attracted particular interest due to their potential for applications in areas as diverse as catalysis, medicine and opto-electronics. The chemical and physical properties of metal nanoparticles can vary smoothly or discontinuously with nanoparticle size, depending on the size regime and the property. In the case of bi- or multimetallic nanoparticles ("nanoalloys"), these properties also depend on the elemental composition and the chemical ordering - how the metals are distributed in the nanoparticles.It is this tunability of behavior that makes metal nanoparticles and nanoalloys so versatile and appealing. This book begins with a tutorial introducing the theoretical ideas and models that have been developed to understand metal nanoparticles. It gives an overview of experimental methods for generating and characterizing metal nanoparticles and nanoalloys and of their properties and applications, providing an introduction to material covered in more depth in subsequent chapters. A major theme of all the chapters is the effect of nanoparticle size, shape and surface chemistry on their properties - especially optical and catalytic properties. A unified discussion of the inter-relations between modelling, synthesis and physical properties of nanoparticles and nanoalloys A discussion of the most promising new catalytic and photocatalytic applications of nanoparticles and the approaches used to achieve these goals A tutorial introduction which provides a basis for understanding the subsequent specialized chapters

Inorganic Electrochemistry Book Review:

Electrochemistry can be an elegant and essential support to synthetic inorganic chemistry. However, it is often perceived as a difficult technique. This book aims to introduce inorganic chemists to electrochemical investigations in as straightforward a way as possible. First, the reader is introduced to the theory of electron transfer processes, how they can be studied by various electrochemical techniques, and the practical procedures required. The book then goes on to look extensively, and with numerous illustrations, at the application of the techniques in the multiple fields of inorganic chemistry (including organometallics, coordination compounds, bioinorganics/biomimetics and materials science). Topics covered include: metallocenes; organometallic and coordination complexes; metal complexes of redox active ligands; metal-carbonyl clusters; superconductors; molecular wires; and proteins. Throughout, special attention is paid to the structural effects accompanying the electron transfer processes. This unique book bridges the gap between undergraduate and research-level electrochemistry books, and will be welcomed as an introduction to electrochemical applications within inorganic chemistry.
