    Naked-Eye-Detectable Supramolecular Sensing System for Glutaric Acid and Isophthalic Acid

    Atsuya Muranaka, Hayato Ban, Masaya Naito, Shinobu Miyagawa, Masahiro Ueda, Shin Yamamoto, Mei Harada, Hikaru Takaya, Masaki Kimura, Nagao Kobayashi, Masanobu Uchiyama, and Yuji Tokunaga

    A porphyrin derivative behaves as a naked-eye-detectable molecular sensor for glutaric acid and isophthalic acid. This molecular sensor binds two molecules of these dicarboxylic acids selectively, with the 1:2 complexes then dimerizing through strong π-stacking interactions of the four aromatic wings at meso positions, accompanied by distinct color changes.

    Phototunable Golden Luster Microcrystalline Film of Photochromic Diarylethene

    Yuma Nakagawa, Ryo Nishimura, Masakazu Morimoto, Satoshi Yokojima, Shinichiro Nakamura, and Kingo Uchida
    https://doi.org/10.1246/bcsj.20220169

    We report the photochromic diarylethene showing a golden luster on a microcrystalline film which is composed of plate-like crystals. A change in luster color upon UV-visible light irradiation is brought about by the photocyclization/photocycloreversion reaction of diarylethene. These results might provide new opportunities for application of photochromic crystals.

    A Cucurbit[6]uril-Based Supramolecular Assembly as a Multifunctional Material for the Detection and Removal of Organic Explosives and Antibiotics

    Xiaodong Han, Shuo Wang, Mei Liu, and Lihui Liu
    https://doi.org/10.1246/bcsj.20220154

    A cucurbit[6]uril-based supramolecular assembly was used for rapid and sensitive detection of nitroaromatic compounds and antibiotics at ppb levels through luminescence quenching. Simultaneously, it also displays high adsorption abilities towards BER. Even more exciting, BER exhibits aggregation induced effect (AIE) functionality with 1 in aqueous solution.

    Novel Ca and Ca-Li Intercalated B/C and B/C/N Materials with Layered Structures

    Masayuki Kawaguchi, Hiromichi Ishikawa, Pascal Berger, Mélissa Fauchard, Sébastien Cahen, and Claire Hérold
    https://doi.org/10.1246/bcsj.20220188

    Calcium (Ca) was intercalated into B/C material through Ca vapor reaction to form intercalation compound with second stage structure (Diagram). While, Ca with lithium (Li) was intercalated into B/C/N material by using Ca-Li alloys to form intercalation compound. The nuclear microprobe analysis is one of the most accurate methods for determining the compositions of these host materials and intercalation compounds.

    Recent Progress in the Synthesis of Deuterated Aldehyde

    Tetsuro Shinada, Atsushi Nakayama, Hironori Okamura, and Yoko Yasuno
    https://doi.org/10.1246/bcsj.20220202

    The deuterium labeling of organic compounds has been extensively studied due to the indispensable role of such compounds in analytical, chemical, and biological studies. This review focuses on recent developments in the synthesis of aldehyde-d1, which is a useful starting material for the synthesis of deuterium-labeled compounds.

    Crystal Structure of a 4,7-Bis(phenylethynyl)-2,1,3-benzothiadiazole-Based Cyclophane and the Mechanoresponsive Luminescence

    Keiko Hiratsuka, Fazil Thuluvanchery Salim, Kiyonori Takahashi, Takayoshi Nakamura, and Yoshimitsu Sagara
    https://doi.org/10.1246/bcsj.20220216

    The crystal structure of the 4,7-bis(phenylethynyl)-2,1,3-benzothiadiazole-based cyclophane was determined. Mechanical grinding to crystalline cyclophane leads to conversion to an amorphous state, and concomitantly, the emission color changes from green to yellow. The subsequent thermal treatment results in a transition to another green-emissive crystalline state. These results suggest that luminescent cyclophanes are good candidates for mechanochromic luminescent materials.

    Neutron Diffraction with 34S/natS Isotopic Substitution Method on the Solvation Structure of S8 Molecule in Concentrated CS2 Solutions

    Yasuo Kameda, Nana Arai, Yuko Amo, Takeshi Usuki, Jihae Han, Hikari Watanabe, Yasuhiro Umebayashi, Seiji Tsuzuki, Kazutaka Ikeda, and Toshiya Otomo
    https://doi.org/10.1246/bcsj.20220221

    Neutron diffraction with 34S/natS isotopic substitution was firstly applied for 6.9 mol% S8-CS2 solutions. Structural parameters within the S8 molecule and those for intermolecular nearest neighbor *S…CS2 interaction have been determined from the observed difference interference function, ΔS(Q). The results agree well with those from MD simulations with newly developed force field parameters for sulfur atoms in S8.

    Negatively Charged Clay Particles Influence Spectroscopic Properties of Anionic Organic Dyes in Aqueous Colloids

    Teruyuki Nakato, Yoshiki Kawanami, Keisuke Taninaka, and Emiko Mouri
    https://doi.org/10.1246/bcsj.20220229

    Negatively charged colloidal particles of smectite clay impact the spectroscopic behavior of anionic dyes. Anionic Eosin B dissolved in clay colloids exhibits absorption and fluorescence maxima red-shifted from the aqueous solution, and the fluorescence is intensified with increasing clay concentration.

    Model Study toward Total Synthesis of Mytilipin C

    Taiki Umezawa, Nurcahyo Iman Prakoso, Koichi Tsuji, Yosuke Ogura, Takumi Sato, and Fuyuhiko Matsuda
    https://doi.org/10.1246/bcsj.20220196

    Synthetic studies on mytilipin C with a model substrate are described. Our study includes three unique reactions: (1) preparation of α,β-chlorinated Weinreb amide from an epoxide precursor and (2) effective formation of a highly functionalized acetylide from the corresponding iodoalkyne. The vicinal coupling constants between α- and β-protons of syn- and anti-α,β-dichlorocarbonyl compounds show small and large values, respectively.

    Expansion of Photocatalytic C(sp3)-H Functionalization to Allylation, Alkynylation, and Imination

    Yi-Lun Shih, Sheng-Hao Huang, Yen-Ku Wu, and Ilhyong Ryu
    https://doi.org/10.1246/bcsj.20220171

    C(sp3)-H allylation, alkynylation, and imination using unsaturated benzenesulfonyl compounds were studied using decatungstate anion, W10O324−, as photocatalyst. In all these reactions, photocatalytic C(sp3)-H bond cleavage was successfully combined with the radical addition and β-scission of phenylsulfonyl radical.

    https://doi.org/10.1246/bcsj.20220146

    The hydrophobic SnO2 films fabricated by chemical bath deposition (CBD) have been modified by trichloropropylsilane (Cl-Si) to enhance the crystalization of MAPbI3 and improve the environment stability, improving the PCE to 20.12% from 17.12%. The PSC modules with an aperture area of 10 cm2 prepared with this strategy achieve an efficiency of 15.24%.
