Autor: Tetsuya Kambe, Shotaro Imaoka, Misa Shimizu, Reina Hosono, Dongwan Yan, Hinayo Taya, Masahiro Katakura, Hirona Nakamura, Shoichi Kubo, Atsushi Shishido, Kimihisa Yamamoto

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-6 (2022)

Borophene exhibits attractive electronic and optical properties, but its instability has so far limited its applications. Here, the authors report the synthesis of a liquid-state borophene analogue showing a good thermal stability up to 350 °C and a

Periodicity of molecular clusters based on symmetry-adapted orbital model

Autor: Takamasa Tsukamoto, Naoki Haruta, Tetsuya Kambe, Akiyoshi Kuzume, Kimihisa Yamamoto

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-8 (2019)

Prediction of stable clusters based on the jellium model is limited because of the usual assumption of their spherical symmetry. Here the authors propose a symmetry adapted orbital model by quantum chemistry calculations for the prediction of stable

Controlled Synthesis of Au25 Superatom Using a Dendrimer Template

Autor: Hisanori Muramatsu, Tetsuya Kambe, Takamasa Tsukamoto, Takane Imaoka, Kimihisa Yamamoto

Publikováno v: Molecules, Vol 27, Iss 11, p 3398 (2022)

Superatoms are promising materials for their potential in elemental substitution and as new building blocks. Thus far, various synthesis methods of thiol-protected Au clusters including an Au25 superatom have been investigated. However, previously re

Nanomaterials design for super-degenerate electronic state beyond the limit of geometrical symmetry

Autor: Naoki Haruta, Takamasa Tsukamoto, Akiyoshi Kuzume, Tetsuya Kambe, Kimihisa Yamamoto

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-6 (2018)

No substances with greater degrees of degeneracy than spherical atoms are known, due to geometrical limitations. In this work the authors combine density functional theory and tight-binding models to predict metal clusters with higher-fold degeneraci

Atom-hybridization for synthesis of polymetallic clusters

Autor: Takamasa Tsukamoto, Tetsuya Kambe, Aiko Nakao, Takane Imaoka, Kimihisa Yamamoto

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-7 (2018)

Multimetallic clusters are difficult to synthesize with control over elemental composition and organization. Here, the authors use dendrimers to precisely template the formation of five-element sub-nanoclusters, providing an elegant route to otherwis

Solution-phase synthesis of Al13 − using a dendrimer template

Autor: Tetsuya Kambe, Naoki Haruta, Takane Imaoka, Kimihisa Yamamoto

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-7 (2017)

Superatoms—clusters that exhibit some of the properties of elemental atoms—could serve as building blocks for functional materials, but their synthesis outside of the gas phase is highly challenging. Here, the authors use a dendrimer template to

Electrochemical C(sp3)−H Functionalization Using Acetic Acid as a Hydrogen Atom Transfer Reagent

Autor: Yuma Morii, Taito Watanabe, Dr. Yutaka Saga, Prof. Dr. Tetsuya Kambe, Prof. Dr. Mio Kondo, Prof. Dr. Shigeyuki Masaoka

Publikováno v: ChemElectroChem, Vol 11, Iss 10, Pp n/a-n/a (2024)

Abstract In this study, we developed a novel electrochemical protocol that enables the functionalization of inherently inert C(sp3)−H bonds. In this protocol, one‐electron oxidation of acetic acid was used to successfully generate methyl radical,
