  Our study on the tetrathiafulvalene-linked 6-oxophenalenoxyl neutral radical
  (S. Nishida, K. Fukui, Y. Morita Chem. Asian J. 2014, 9, 500-505, DOI: 10.1002/asia.201301188) has appeared as a Cover Picture.
  The continuous color change of the solution of the neutral radical occurring with the temperature-dependent ΔE shift is expressed as an autumn leaf color.

  Hydrogen-Bonding Effect on Spin-Center Transfer of Tetrathiafulvalene-Linked 6-Oxophenalenoxyl Evaluated Using Temperature-Dependent
  Cyclic Voltammetry and Theoretical Calculations

  The article on the hydrogen-bonding effect on spin-center transfer of tetrathiafulvalene (TTF)-substituted 6-oxophenalenoxyl neutral radicalhas been published as Full paper in Chem. Asian J.
  We have successfully observed a change in the redox potentials involved in the spin-center transfer of the neutral radical with decrease in temperature using a conventional low-temperature electrochemical cell we designed and fabricated.
  Furthermore, theoretical calculations indicated that hydrogen-bonding interaction by 2,2,2-trifluoroethanol as solvent promotes the spin-center transfer.

  Control of Exchange Interactions in π Dimers of 6-Oxophenalenoxyl Neutral π Radicals: Spin-Density Distributions and Multicentered–Two-Electron Bonding Governed by Topological Symmetry and Substitution at the 8-Position
  Nishida, S.; Kawai, J.; Moriguchi, M.; Ohba, T.; Haneda, N.; Fukui, K.; Fuyuhiro, A.; Shiomi, D.; Sato, K.; Takui, T.; Nakasuji, K.; Morita, Y.
  Chem. Eur. J. 2013 , 19, 11904-11915
  The first article on the crystal structures and the solid-state properties of 6-oxophenalenoxyl derivative,stable neutral radicals we designed and synthesized, has been published as Full paper in Chem. Eur. J. These radicals form π dimers in the crystalline state similar to tri-tert-butylphenalenyl radical, while the intradimer exchange interactions are very small due to change in topological symmetry of spin density distribution and substituents on the 8-position.
