1. Yoshiaki Shoji, Naoki Tanaka, Yasuhiro Ikabata, Hayato Sakai, Taku Hasobe, Norbert Koch, Hiromi Nakai, Takanori Fukushima, Tetraaryldiborane(4) Can Emit Dual Fluorescence Responding to the Structural Change around the B–B Bond, Angewandte Chemie International Edition, 2021.10, ジメシチルボリニウムイオンの還元的カップリングにより、これまで単離が困難であったテトラメシチルジボラン(4)(Mes4B2)の合成に成功した。メシチル基による立体保護により、Mes4B2は化学的に極めて安定であり、水中でも安定に存在できる。Mes4B2は、溶液中でも固体状態でも460nmと620nmの二重蛍光を有することが明らかになった。理論計算の結果、励起S1状態のMes4B2はねじれた形状または平面形状をとり、それぞれ短波長蛍光または長波長蛍光の原因であることがわかった。二重蛍光の強度比は媒体の粘度に敏感であることから、この特徴を利用してMes4B2は粘度センサーとしての可能性が示唆された。.
2. Naoki Tanaka, Aoi Hamasuna, Takuto Uchida, Ryohei Yamaguchi, Taiki Ishii, Aleksandar Staylkov, Tsuyohiko Fujigaya, Electron doping of single-walled carbon nanotubes using pyridine-boryl radicals, Chemical Communications, 10.1039/D1CC01354H, 57, 49, 6019-6022, 2021.05, Pyridine-boryl (py-boryl) radicals serve as efficient electron-doping reagents for single-walled carbon nanotubes (SWCNTs). The doping mechanism comprises electron transfer from the py-boryl radical to the SWCNT. The formation of a stable py-boryl cation is essential for efficient doping; the captodative effect of the py-boryl cation is important to this process..
