Disclosed is a novel organic compound synthesized by oligomerizing or polymerizing a specific quinone compound having two quinone groups at the ortho position and having a property such that the electron transfer occurs associated with a reversible redox reaction, the organic compound being insoluble in an organic solvent and having a high energy density, and thus being useful as an electrode active material for a power storage device. Using this organic compound as an electrode active material can improve the energy density, reduce the weight and size, and improve the functionality of the power storage device.

A general and efficient protocol for the synthesis of 9,10-phenanthraquinone derivatives has been successfully developed involving a copper(0)/Selectfluor system-promoted oxidative carbon–carbonbond cleavage/annulation of o-aryl chalcones. A variety of substituted 9,10-phenanthraquinones were synthesized in moderate to good yields under mild reaction conditions.

a novel strategy for the direct construction of polycyclic fused ortho-quinone scaffolds through palladium(II)-catalyzedtandem γ-C(sp2)–H arylation and cyclization of arylglyoxals with aryl iodides. This transformation features unique tandem transient directing of γ-C(sp2)–H arylation and cyclization reaction mode, broad substrate scope, especially for the aromatic substrates containing oxygen and
