Paragraph 0047-0051, (2021/01/30)
The invention relates to an organic electrode material and a preparation method and application thereof, and belongs to the technical field of materials. The organic electrode material belongs to conjugated carboxylate. The material is used as a working electrode of a sodium ion battery, the specific discharge capacities of an organic electrode material I-1 and an organic electrode material I-2 are 171mAh. g and 184mAh.g respectively after 100 cycles at the current density of 100mA/g, and half batteries prepared by taking I-1 and I-2 as the electrode materials can provide high specific capacity of 119mAh/g and 90mAh/g respectively in a voltage platform test process when 5C is 935mA/g. And the working voltages of the two materials both are between 0.4V and 0.7 V. The electrodematerial prepared by the method can be well applied to the sodium-ion battery, and has excellent oxidation-reduction capability and cycling stability when used as a negative electrode material. The organic electrode material is simple in preparation process and low in cost, and meets the requirement of large-scale preparation.

Decarboxylative cross-coupling of 3-pyridyl and 4-pyridyl carboxylates with aryl bromides is reported. Using a bimetallic system of Cu2O and Pd(PPh3)4, the scope of the reaction is demonstrated by the synthesis of 27 pyridine-containing biaryls in moderate to good yields.

This research was undertaken to explore the interior surface of a synthetic receptor 1.1 with arylpyridines as guests. The interior surface differentiates the guests through the recognition of their nitrogen atoms. Experimental and computational analyses revealed that there is a delicate balance of attractions and repulsions between the host and the lone pairs of guests.
