Diradicals or Zwitterions: The Chemical States of m-Benzoquinone and Structural Variation after Storage of Li Ions

m-Benzoquinones are often regarded as unstable materials in the form of radicals. Herein, an air-stable small molecular m-benzoquinone [4,6-diamino-1,3-benzoquinone (4,6DA1,3BQ)] without bulky grou...
