[0031] In the present invention, the crosslinking reaction is preferably carried out in an organic solvent, and the organic solvent preferably includes diethyl ether and / or ethyl acetate. The present invention preferably prepares 1,2-bis(4-pyridyl)ethylene and cyanuric chloride re...

Embodiment 1

[0039]Using 1,2-bis(4-pyridyl)ethylene and cyanuric chloride as the main starting materials and ethyl acetate as the solvent to prepare ionized nanoporous organic network polymer: 1.138g of cyanuric chloride was dissolved in 30mL Prepare solution A in ethyl acetate; dissolve 1.638g of 1,2-bis(4-pyridyl)ethylene in 50mL of ethyl acetate to prepare solution B. Solution A was added dropwise into solution B at a stirring speed of 400 rpm. Then, the temperature of the mixed solution was raised to 100° C., and reacted under this condition for 48 hours. After the reaction was over, the precipitate was obtained by filtration. The precipitate was washed in 50 mL of ethyl acetate, filtered, and the above washing was repeated 3 times. The product was then dried in a vacuum oven to obtain a brown ionized nanoporous organic network polymer with a yield of 91%.

Description

technical field [0001] The invention belongs to the technical field of nanometer materials, and in particular relates to an ionized nanoporous organic network polymer and its preparation method and application. Background technique [0002] In recent years, ionized nanoporous organic network structures (NIONS) have been gradually paid attention to by academic and industrial circles as a new type of functionalized materials with wide applications due to their structures containing abundant anion / cation units. Compared with traditional polymer materials, this kind of material not only utilizes its own dynamic ionic bonding and anion and cation exchange characteristics to regulate the channel function, but also can use Coulomb interaction, ion π interaction and ion bridging effect to enhance the interaction between the guest and the host. Molecular selective recognition capabilities. For example, Zhang Yuanjian et al. through porous C 3 N 4 The introduction of ionic charges ...
