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...
