13 results about "Conjugated microporous polymer" patented technology

Conjugated microporous polymers (CMPs) are a sub-class of porous materials that are related to structures such as zeolites, metal-organic frameworks, and covalent organic frameworks, but are amorphous in nature, rather than crystalline. CMPs are also a sub-class of conjugated polymers and possess many of the same properties such as conductivity, mechanical rigidity, and insolubility. CMPs are created through the linking of building blocks in a π-conjugated fashion and possess 3-D networks. Conjugation extends through the system of CMPs and lends conductive properties to CMPs. Building blocks of CMPs are attractive in that the blocks possess broad diversity in the π units that can be used and allow for tuning and optimization of the skeleton and subsequently the properties of CMPs. Most building blocks have rigid components such as alkynes that cause the microporosity. CMPs have applications in gas storage, heterogeneous catalysis, light emitting, light harvesting, and electric energy storage.

PendingCN122144705ACell electrodesSecondary cellsIonic diffusionPtru catalyst
The application relates to a nitrogen-doped multi-level microporous carbon material and a preparation method thereof, and belongs to the technical field of carbon materials. A conjugated microporous polymer of an alkyne porphyrin is obtained by coupling reaction of a halogenated aromatic hydrocarbon containing bromine and an alkyne benzene compound under the joint action of copper and palladium catalysts. By pyrolysis at different temperatures, some functional groups in the polymer are cracked and escape in the form of gas, which continuously forms pores in the carbon skeleton and gradually changes into a nitrogen-doped multi-level microporous carbon material. The nitrogen-doped sites in the structure of the multi-level microporous carbon material generate defect sites and provide a large number of active sites; meanwhile, the multi-level microporous structure forms a three-dimensional through structure between pores, effectively shortening the ion diffusion path; pyrolysis can change the polymer skeleton into a short-range ordered structure, providing an interlayer embedding channel for ions; and the energy storage mechanism of the material is defect adsorption, interlayer embedding and micropore filling respectively.
