High-capacity metal ion battery organic electrode material, and preparation method and application thereof

The invention belongs to the field of ion battery electrode materials, and particularly relates to a high-capacity metal ion battery organic electrode material, and a preparation method and application thereof. The metal ion battery organic electrode material is an organic conjugated compound containing hexaazabenzene and a quinone functional group, the organic conjugated compound contains a plurality of redox active sites, and the theoretical capacity is greater than 500mAh g. The novel conjugated organic electrode material is obtained by carrying out dehydration condensation on the quinonoid compound of o-phenylenediamine and cyclohexanehexone. When the obtained conjugated organic electrode material is used as an aqueous zinc ion battery, high-specific-capacity output and excellent cycling stability and rate capability are realized, and the capacity reaches up to 430 mAh g under the current density of 100 mA g. The conjugated organic material designed by the invention solves the technical problems of lower capacity and poorer rate capability when the existing organic material is used as a zinc ion battery electrode material, and is expected to be used in the field of next-generation environment-friendly and high-energy-density energy storage batteries.

Reagent Design and Study of p-Benzoquinone Derivatives. The Site-Selective Cycloaddition Reaction of Diquinones and Photochemical Cage Formation of the Adducts

Cycloaddition reactions of naphthodiquinone derivatives and the photochemical behavior of their adducts have been investigated.Naphthodiquinone (4) and dichloronaphthodiquinone (5) reacted exclusively at the internal double bond with both cyclopentadiene and quadricyclane to give the corresponding 1:1 adducts in high yields.While anthradiquinone (6) reacted also only at the internal double bond with quadricyclane, the reaction with cyclopentadiene took place at both the internal and terminal double bonds of 6.The stereochemistry of the adducts was determined by spectral inspections and chemical transformations.The cyclopentadiene adducts were photochemically converted into the cage compounds in high yields, although the quadricyclane adducts were photoinert.In the photochemical reactions, high site selectivity was observed; the intramolecular ? photoaddition occurred only between enedione (electron poor) and cyclopentene (electron rich) double bonds.
