Abstract

The invention provides a conjugated microporous polymer adopting ketone-enamine bond connection and a preparation method thereof. The structure of a repetitive unit of the conjugated microporous polymer is shown in the formula (I) (shown in the description). The preparation method of the conjugated microporous polymer adopting the ketone-enamine bond connection comprises the following steps: fully mixing 2, 4, 6-trialdehyde phloroglucinol and an acetic acid aqueous solution under the oxygen-free condition, and adding m-phenylenediamine for reaction, so as to obtain the conjugated microporous polymer adopting ketone-enamine bond connection, of which the repetitive unit has a structure shown in the formula (I) (shown in the description). Compared with the prior art, the conjugated microporous polymer and the preparation method have the benefits as follows: 1, the conjugated microporous polymer adopting the ketone-enamine bond connection, synthesized by the preparation method for the first time has higher specific surface area and high stability, and has wide prospect in the fields of carbon dioxide adsorptive separation and the like; 2, the preparation method is environment-friendly, pollution-free and simple in equipment requirements, thereby being suitable for industrialized large-scale production.

Description

technical field [0001] The invention relates to a conjugated microporous polymer connected by ketone, enamine bonds, and belongs to the technical field of polymer materials. Background technique [0002] Conjugated Microporous Polymer (CMPs) is a class of compounds with special microporous structure, large specific surface area, structural diversity and adjustable physical and chemical properties. Through literature retrieval of the prior art, it was found that in 2007, JIANG et al reported the microporous polyamide polyamine epichlorohydrin resin (ConjugatedMicroporousPoly(arylenethynylene) Networks ) synthesis, its specific surface area is as high as 834m 2 / g. Due to their unique properties and potential applications, this kind of microporous materials has attracted extensive attention and research. Compared with common organic porous materials, CMP has a large specific surface area, excellent chemical stability, good thermal stability, structural adjustability, etc., ...
