The invention discloses a conjugated organic lithium ion battery electrode material and a preparation method and application thereof, and belongs to the technical field of lithium ion batteries. Firstly, a compound 1 is subjected to acid hydrolysis to synthesize a compound 2, the compound 2 reacts with TFA, NaNO2, NaHCO3 and NaOH and then reacts with HCl to obtain H6-HAT, excessive lithium hydroxide is added for a reaction, and finally the derivative Li6-HAT of 1, 4, 5, 8, 9, 12-hexaazabenzophenanthrene (HAT) is obtained. When the conjugated organic electrode material Li6-HAT is used for a lithium ion battery electrode, the first specific discharge capacity reaches 1126mAh/g under the current density of 0.01 V-3V and 100mA/g; and the discharge capacity is 588.0 mAh/g after 50 cycles. The synthesized conjugated organic electrode material is novel and stable in structure and is a novel lithium ion battery electrode material.

Charge-transfer (CT) π-complexes are formed between planar porphyrins and 1,4,5,8,9,12-hexaazatriphenylene (HAT) derivatives with large formation constants (e.g., 104 M-1), exhibiting broad CT absorption bands. The unusually large formation constants result from close face-to-face contact between two planar π-planes of porphyrins and HAT derivatives. The redox potentials of porphyrins and HAT derivatives measured by cyclic voltammetry indicate that porphyrins and HAT derivatives act as electron donors and acceptors, respectively. The formation of 1:1 CT complexes between porphyrins and HAT derivatives was examined by UV-vis, fluorescence and 1H NMR measurements in nonpolar solvents. The occurrence of unprecedented ultrafast photoinduced electron transfer from the porphyrin unit to the HAT unit in the CT π-complex was observed by femtosecond laser flash photolysis measurements. A highly linear aggregate composed of a planar porphyrin and an HAT derivative was observed by transmission electron microscopy (TEM) and atomic force microscopy (AFM).

In this paper, we report for the first time the synthesis of hexaazatriphenylenehexacarbonitrile, abbreviated HAT-hexacarbonitrile.This hydrogenless, symmetrically branched compound can be prepared in analytically pure form on a large scale by using commercially available starting materials.The conversions of HAT-hexacarbonitrile to the corresponding hexaamide, hexaacid, hexaester, and trianhydride derivatives were also accomplished.
