摘要:The present invention provides a series of ionic vinyl covalent organic framework materials constructed in two ways by means of designing a novel method. Such materials feature high crystallinity and specific surface area, cost-efficiency, simple synthesis, capability of self-forming and mass production, and the like. The synthesis process avoids the use of organic solvents and thus the risks of high pressure during the reaction process, and thereby possesses suitability for mass production and industrial potential. In addition, the ionic COF materials have the capability of efficiently isolating oxygen-containing anions from water, and have great industrial application prospects.
