  • Electronic properties of transition metal-benzene sandwich clusters

    Tsugunosuke Masubuchi, Atsushi Nakajima, Springer Singapore, 2020.01

     View Summary

    Organometallic clusters composed of transition metal atoms and benzene molecules have been topics of great interest from both fundamental and technological points of view. In this chapter, we review the progress in the physical chemistry of transition metal-benzene clusters. The intrinsic properties of transition metal-benzene clusters as a function of cluster size are investigated by gasphase experiments, often in combination with quantum chemical calculations. In particular, vanadium-benzene clusters denoted VnBzm, showing magic numbers at m = n + 1, n, and n – 1, are characterized to possess multiple-decker sandwich structures, where vanadium atoms and benzene molecules are alternately piled up. Moreover, the discovery of such multiple-decker formation is a cornerstone in bottom-up approaches of molecular magnetism. The interplay of mass spectrometry, laser spectroscopies, and density functional calculations reveals that multiple-decker VnBzm clusters exhibit monotonic increase in magnetic moment with the number of layers. Anion photoelectron spectroscopic studies allow direct observations of the geometric and electronic structures of sandwich clusters and their anions. Major progress in this direction includes the recent characterization of tilted multipledecker sandwich cluster anions composed of manganese atoms and benzene molecules. The sandwich clusters with high-spin characteristics will hopefully be exploited as building blocks in advanced electronic and magnetic nanomaterials via controlled assembly.

  • Superatomic Nanoclusters Comprising Silicon or Aluminum Cages

    Nakajima A., Physical Chemistry of Cold Gas-Phase Functional Molecules and Clusters, 2019.01

     View Summary

    This chapter describes two superatoms, each comprising a central atom and a silicon or aluminum cage. Binary nanoclusters (NCs) at optimized mixing ratios are key components in designing the functionalities relevant to their electronic properties. To form chemically robust functional NCs, it is important to design the cooperatively synergistic effects between the electronic and geometric structures because these stabilize the individual NCs not only against charge transfer into the corresponding cations or anions but also against structural perturbations in their assemblies. Among binary NCs, synergistic effects are particularly expected when one central atom encapsulating cage structure completes a specific electron shell because electronic and geometric factors can operate simultaneously. Although the term “superatom” is widely used when the valence electrons in NCs complete an electron shell, more synergistic effects appear when the superatom adopts a closepacked structure, such as a highly symmetric cage as a binary cage superatom. Representative examples are given for one central atom encapsulated by silicon and aluminum cages, M@Si16 and X@Al12, their formation and characterization are described, and a large-scale synthetic approach is established for M@Si16. The perspectives for binary cage superatom assembly are discussed in terms of theoretical calculations.

  • Experimental Methods: Generation of Cold Gas-Phase Molecules, Molecular Ions, Their Clusters, Metal Clusters, and Laser Spectroscopy

    Ebata T., Inokuchi Y., Nakajima A., Physical Chemistry of Cold Gas-Phase Functional Molecules and Clusters, 2019.01

     View Summary

    In this chapter, we describe the methods of generating cold neutral andionic (cation and anion) molecules, their clusters, and metal clusters in the gasphase. First, a technique of supersonic free-jet or supersonic beam to generate cold neutral molecules and clusters is described. In addition, heating and laser ablation nozzles for the geneation of supersonic free-jet of nonvolatile molecules, such as high melting point and bio-related molecules, are introduced, while the methods of laser ablation and magnetron sputtering to generatemetal clusters are also described. We then introduce various laser spectroscopic methods to measure the electronic and vibrational spectra for the jet-cooled molecules. Laser-induced fluorescence (LIF) and resonance-enhanced two-photonionization (R2PI) spectroscopy is used to measure the electronic spectrum. UV-UV hole-burning (UV-UV HB) spectroscopy is used to discriminate the electronic transitions of different conformers and isomers. For the measurement of the vibrational spectrum of a specific molecule or cluster, we apply infrared-ultraviolet double-resonance (IR-UV DR) spectroscopy. If the molecule has no chromophore, a combination of IR and vacuum UV laser light (IRVUV) is used to obtain the vibrational spectrum. Second, we describe the generation methods of gas-phase coldionic molecules and clusters. The gas-phaseions are generated by resonant-enhanced multi-photonionization, electron impact, electron attachment, matrix-assisted laser disorption/ionization (MALDI), and electrosprayionization (ESI). Cooling of theions is achieved by supersonic expansion or by the use of cryogenically cooledion-trap. A time-of-flight (TOF) mass spectrometry or quadrupolemass filter is used for themass selection, which is also applicable to obtain the single-sized metal clusters selectively. To obtain the electronic and vibrational spectra of theionic species, we apply UV photodissociation (UVPD) and IR multiphoton dissociation (IRMPD), respectively. IR-UV DR spectroscopy is also used to measure the IR spectrum of a specificion. In addition to the detection of theions, a measurement of the photo-ejected electron, called photoelectron spectroscopy, is also described. Finally, we introduce pump-probe spectroscopy to investigate the dynamics of the vibrationally and electronically excited molecules and clusters.

  • Formation of Superatom Monolayer Using Nanocluster Ion Source Based on High-Power Impulse Magnetron Sputtering

    A. Nakajima, Encyclopedia of Interfacial Chemistry: Surface Science and Electrochemistry, 2018.01

     View Summary

    The assembled monolayer of superatomic nanocluster ions synthesized in the gas phase is formed with monodispersive immobilization of Ta atom-encapsulated Si16 cage superatom (Ta@Si16) with an intensive ion source based on high-power impulse magnetron sputtering (HiPIMS). Scanning tunneling microscopy and spectroscopy have demonstrated that superatom cations of Ta@Si16+ can be densely immobilized on C60-terminated surfaces while retaining their cage shape by forming charge transfer (CT) complexes ((Ta@Si16)+C60-) on the surfaces. Its chemical states of Ta@Si16 deposited on an electron acceptable C60 fullerene film were evaluated by X-ray photoelectron spectroscopies (XPS). XPS results for Si, Ta, and C elements showed that Ta@Si16 combines with a single C60 molecule to form (Ta@Si16)+C60-. The high thermal and chemical robustness of the superatomic CT complex has been revealed by the XPS measurements conducted before and after heat treatment and oxygen exposure. The formation of robust superatom monolayer with HiPIMS demonstrates that the superatoms including metal-encapsulating silicon cage superatoms have a promising potential to be utilized for building blocks of novel functional nanomaterials.

  • Transition Metals in Silicon Cages: Shrinking to M@Si15 (M = Re, Os, Ir)

    T. Ichikawa, K. Terasaka, A. Sasaki, A. Nakajima

    Journal of Physical Chemistry Letters (American Chemical Society)  15 ( 46 ) 11678 - 11686 2024.11

    Research paper (scientific journal), Joint Work, Last author, Corresponding author, Accepted

     View Summary

    The design of materials with intriguing electronic properties is crucial for advancing nanoscale technologies, where precise control over atomic structure and electronic behavior is essential. Metal-encapsulating silicon cage superatoms (SAs) provide a new paradigm for molecular-scale material design, allowing fine-tuning of both structure and electronic characteristics. The formation of superatoms mimicking halogens, noble gases, and alkali metals has been well-studied, particularly with M@Si16, where early transition metals from groups 3 to 5 stabilize within a Si16 cage, achieving a 68-electron configuration. For late transition metals with excess electrons, a Si15 cage offers enhanced stability by fulfilling the 68-electron rule with one fewer Si atom. This research synthesizes Si15 cage-SAs with rhenium (Re) from group 7 and iridium (Ir) from group 9 on p-type and n-type organic substrates. The stability of Re@Si15 and Ir@Si15 is evaluated via oxidative reactivity with X-ray photoelectron spectroscopy and theoretical calculations, including osmium (Os) from group 8. Re@Si15-, Os@Si150, and Ir@Si15+ exhibit superatomic behaviors similar to halogens, noble gases, and alkali metals due to the 68-electron shell closure. Among them, Re@Si15- on p-type organic substrates shows superior electronic and geometric properties. These findings advance our understanding of M@Sin systems for transition metals, addressing longstanding questions about their properties at n = 15 and 16.

     View Summary

    Superatoms (SAs) with specific compositions have the potential to significantly advance the field of nanomaterials science, leading to next-generation nanoscale functionalities. In this study, we fabricated assembled layers with tantalum metal-atom encapsulating silicon cage (Ta@Si16) SAs on an organic C60 substrate through deposition, and we characterized their electronic and optical properties by photoelectron spectroscopy and microscopy. The alkaline nature of Ta@Si16 SAs reveals their electronic behaviors, such as charge transfer and electromagnetic near-field sensing, through two-photon photoemission (2PPE) spectroscopy and microscopy with a femtosecond laser. The evolution of the work function for Ta@Si16 SAs on C60, observed by 2PPE spectroscopy, demonstrates charge transfer complexation between the topmost C60 layer and the first Ta@Si16 layer, consistent with the electron-donating alkaline characteristics of Ta@Si16 SAs. Specifically, a small amount of Ta@Si16 SA deposition leads to a dramatic increase in 2PPE intensity, attributable to electromagnetic near-field enhancements, suggesting applications as sensitizers for nonlinear imaging in photoemission microscopy. For the assembled Ta@Si16 SA layers, a plasmonic response of hνp = 17.9 eV is spectroscopically identified, including their valence and conduction band structures, and the plasmonic energetics are discussed in the context of metal doping in bulk silicon.

  • Geometric and Electronic Properties of P Atom-Doped Al Nanoclusters: Alkaline-like Superatom of P@Al12

    M. Akutsu, K. Koyasu, K. Miyajima, M. Mitsui, T. Inoue, A. Nakajima

    Journal of Physical Chemistry A (American Chemical Society (ACS))  128 ( 32 ) 6648 - 6657 2024.08

    Research paper (scientific journal), Joint Work, Last author, Corresponding author, Accepted,  ISSN  10895639

     View Summary

    The geometric and electronic characteristics of phosphorus-atom doped aluminum nanoclusters, AlnPm (n = 7-17, m = 1 and 2), were investigated through a combination of experiments and theoretical calculations. The size dependences of the ionization energy (Ei) for AlnPm NCs exhibit a local minimum of 5.37 eV at Al12P1, attributed to an endohedral P@Al12 superatom (SA). This SA originates from an excess electron toward the 2P shell closing (40e), coexisting with an exohedral isomer featuring a vertex P atom. The stability of the endohedral P@Al12 is further enhanced in its cationic state compared to the exohedral isomer, when complexed with a fluorine (F) atom, forming an SA salt denoted as P@Al12+F- with an elevated Ei ranging from 6.42 to 7.90 eV. In contrast, for the anionic Al12P1-, the exohedral form is found to be more stable than the endohedral one using anion photoelectron spectroscopy and calculations. The geometric and electronic robustness of neutral P@Al12 SAs against electron donation and acceptance is discussed in comparison to rare-gas-like Si@Al12 SAs.

  • Imaging of Ultrafast Photoexcited Electron Dynamics in Pentacene Nanocrystals on Graphite Substrat

    Masahiro Shibuta, Atsushi Nakajima

    Nanoscale (Royal Chemical Society)  16 ( 26 ) 12397 - 12405 2024.05

    Research paper (scientific journal), Accepted,  ISSN  20403364

     View Summary

    Understanding molecular film growth on substrates and the ultrafast electron dynamics at their interface is crucial for advancing next-generation organic electronics. We have focused on studying the ultrafast photoexcited electron dynamics in nanoscale organic crystals of an aromatic molecule, pentacene, on a two-dimensional material of graphite substrate. Through the use of time-resolved two-photon photoelectron emission microscopy (2P-PEEM), we have visualized the ultrafast lateral evolution of photoexcited electrons. By resonantly tuning the incident photon to excite pentacene molecules, polarization-dependent 2P-PEEM has revealed that pentacene nanocrystals (sub- to several μm) on the substrate exhibit a preferential orientation, in which a molecular π-orbital contacts the substrate in a “lying flat” orientation, facilitating electron transfer to the substrate. The time-resolved 2P-PEEM captures the motion of excited electrons in a femto- to pico-second timescale, clearly imaging the ultrafast charge transfer and lateral expansion two-dimensionally on the graphite substrate. Moreover, we found that the lying-flat molecular orientation of pentacene nanocrystals is transformable into a “standing-up” one through gentle heating up to 50 °C. These experimental insights using time-resolved 2P-PEEM will be highly valuable in enhancing the photofunctionalities of organic electronic devices by controlled molecular deposition.

     View Summary

    <p>Intensive ion source for single-size nanoclusters was developed on the basis of high-power impulse magnetron sputtering (HiPIMS) technique combined with a low-pressure, low-temperature gas flow reactor. The nanocluster source exhibits superior characteristics originating from pulsed, high-power sputtering compared to conventional direct-current sputtering; (1) enhanced ion intensities, (2) fascicle tuning of nanocluster sizes, and (3) enhanced selectivity of stable, magic nanoclusters. The metallic (silver, platinum, and palladium) and binary (transition-metal and silicon) nanocluster ions in the size range of several to one hundred atoms can be generated with ion current of 100 pA to 10 nA (108 to 1011 nanoclusters/sec). The growth mechanism of nanoclusters in the source was also explained by the nucleation theory.</p>

    ISSN  10895639

     View Summary

    A two-laser vaporization method produced novel lanthanide organometallic culsters, Lnn(C60)m, consisting of lanthanide atoms (Ln; Ln = Eu and Ho) and C60 molecules in the gas phase. The Lnn(C60)m clusters were produced predominantly at compositions of (n,m) = (n, n + 3) [n = 1-4]. These stoichiometries revealed no chemisorption reactivity toward CCl4 and O2 reactants. The cluster having (1,4) composition was proposed to form a tetrahedral structure, in which a Ln atom was surrounded by four C60 molecules. In larger clusters with (n, n + 3) composition, each Ln atom was in a local (1,4) group. Ln1(C60)m clusters were charge-transfer complexes expressed as Ln1x+(C60)mx+, and that Eu and Ho atoms existed as Eu2+ and Ho3+ ions, respectively.
