Embodiment 1

[0034] A preparation method of a conductive conjugated microporous polymer sample 1 comprises the following steps;

[0035] Step 1, preparation of conjugated microporous polymer: bromoarene monomer 1,3,5-tris(4-bromophenyl)benzene (2 mmol), 1,4-phenyldiboronic acid (3 mmol mol), potassium carbonate (10 mmol), and tetrakis(triphenylphosphine) palladium (0.6 mmol%) were mixed and dissolved in 100 ml of dimethylformamide, and heated to 150° C. for 48 hours under argon protection. The resulting suspension was cooled to room temperature, poured into water, and the precipitate was collected by filtration, purified with a Soxhlet extractor using water, methanol, and tetrahydrofuran as solvents for 3 days, and dried in vacuo.

[0036] Step 2, disperse 100 mg of conjugated microporous polymer in 50 ml of dichloromethane solution containing pyrrole, wherein the mass ratio of conjugated microporous polymer to pyrrole is 1:1. Then, the solvent was removed by evaporation to obtain a pyrro...

Description

technical field [0001] The invention relates to the technical field of conductive microporous materials, in particular to a conductive conjugated microporous polymer and a preparation method thereof. Background technique [0002] The International Institute of Purity and Applied Sciences (IUPAC) divides porous materials into three categories according to the pore size: materials with a pore size less than 2 nm are microporous materials, materials with a pore size between 2 and 50 nm are mesoporous materials, and materials with a pore size above 50 nm The material is a macroporous material. Porous organic polymer material is a new type of polymer porous material with microporous or mesoporous structure formed by organic structural units connected by covalent bonds. The pore structure is unique and can accommodate multiple functional groups in the same network structure at the same time. , and has promising research prospects in many fields such as gas storage, separation, an...
