Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The new method for rapidly preparing the organic porous material based on the styryl monomer by adopting cationic polymerization, provided by the invention, is characterized in that a binary or multi-element styryl compound is dispersed in a halogenated hydrocarbon solvent, and an organic porous polymer is obtained under the action of a catalyst, the method is mild in reaction conditions, the reaction temperature is 0-40 ℃, the reaction time is 5 min-36 h, and the organic porous polymer is obtained by separation and purification. The binary or poly styryl compound is one or more aromatic compounds containing binary or poly styryl. The invention takes binary or multi-element styryl aromatic ring compounds dispersed in organic solvent as raw materials, under the catalysis of Lewis acid or protonic acid, carbocationic active species are formed, ion pairs are formed with counter ions, the binary or multi-element styryl aromatic ring compounds are used as monomers to be inserted into the ion pairs to initiate cationic polymerization, and the organic porous polymer is obtained after separation and purification. When the protonic acid is used as a catalyst, the protonic acid is partially ionized to generate protons and anions, and the protons protonate vinyl in the styryl aromatic ring compound to form carbocationic active species which form ion pairs with the anions in the protonic acid; when Lewis acid is used as a catalyst, the Lewis acid and halogenated alkane solvent are complexed to form an ion pair, carbon in the halogenated alkane forms carbocation active species, halogen is counter ion, finally the monomer is inserted into the ion pair to initiate cation polymerization, and the organic porous polymer is obtained after separation and purification.
The above-mentioned binary or polybasic styryl compound is a polymerization monomer for the polymerization reaction of the present invention, and the selection of the polymerization monomer has a direct influence on the specific surface area, pore size distribution and functionality of the polymer. The applicant of the present invention finds in experiments that both binary and poly styrene-based monomers can be rapidly polymerized to obtain an organic microporous polymer, the larger the length of the monomer is, the larger the pore size of the formed monomer is, which directly affects the surface area, and the functional monomer can impart different functionalities to the prepared polymer.
Preferred vinyl compounds in the present invention are aromatic compounds of di-or poly-styryl group, including linear aromatic styryl compounds such as divinylbenzene; also included are branched chain polyphenylvinylaromatics, such as tris (4-vinylbiphenyl) amine, 1,3,6, 8-tetrakis (4-vinylphenyl) pyrene.
The solvent used in the preparation method of the organic porous polymer is a halogenated solvent, preferably one or more of chloromethane, dichloromethane, dichloroethane, trichloromethane or carbon tetrachloride.
The applicant of the invention finds in experiments that the monomer polymerization can be catalyzed by using Lewis acid or protonic acid as a catalyst, wherein anhydrous aluminum trichloride, anhydrous ferric trichloride, anhydrous stannic chloride, anhydrous zinc chloride and concentrated sulfuric acid can catalyze the polymerization reaction. The anhydrous ferric chloride and the anhydrous aluminum trichloride have the highest catalytic activity and the fastest reaction rate, the catalytic activity of zinc chloride is low, and dilute sulfuric acid cannot catalyze the reaction, because the content of water in the dilute sulfuric acid is too high, the water can quench a cation active center.
The control of the dosage of the catalyst is more critical. The dosage of the catalyst is too low, the catalytic activity is not high, and the reaction efficiency is low; if the concentration of the catalyst is too high, the catalyst residue is caused, the post-treatment is very difficult, and the catalyst is difficult to remove completely, so that the specific surface area of the product is reduced, and the performance of the porous polymer is influenced; and the catalyst is metal halide, so that the catalyst is corrosive to the organic porous polymer, and the application of the organic microporous polymer is limited. The ratio of the content of styryl in the binary or poly styryl compound to a catalyst such as a Lewis acid is 1: 0.25-4, preferably 1: 0.5-4, the reaction process is a cationic polymerization process, the polymerization rate is very high, and therefore, the polymerization degree can be adjusted by the polymerization time so that the prepared polymers have different specific surface areas.
The reaction temperature is-100-40 ℃, and the reaction temperature is preferably 0-40 ℃ in consideration of the operability of the reaction and reduction of chain transfer; the formation of the polymer needs a certain time, so that the reaction time is properly prolonged to be beneficial to the formation of the polymer chain, but when the arrangement of the polymer molecular chains is completed or the stacking process is completed, the subsequent reaction time has little significance to the reaction, and the proper reaction time is 5min to 36h, preferably 12 to 24 h. Since the reaction occurs according to cationic polymerization, the reaction speed is very fast, and thus the specific surface area of the polymer can be adjusted by controlling the reaction time.
After the reaction is finished, the separation and purification is to add a large amount of methanol or ethanol for quenching, then carry out suction filtration until the filtrate becomes colorless, then carry out extraction for 24 hours by using methanol or ethanol, and then dry for 24 hours at 60 ℃.
The applicant of the present invention discusses and reasons the mechanism of the above preparation method, and explains the reaction mechanism by using styrene as a model molecule and 1,3,6, 8-tetra (4-vinylphenyl) pyrene as a monomer, and as shown in fig. 1, the polymerization process is divided into three processes: (1) chain initiation: first forming a complex with a proton donor or a carbocation donor under the action of a catalyst, and then initiating a monomer, (2) chain extension: the carbocationic active species generated by chain initiation form ion pairs with counter ions, monomer molecules are inserted into the ion pairs to grow, and (3) chain termination: artificially terminated by the addition of water, ethanol or methanol. However, styrene cannot be used as a monomer for preparing the organic porous polymer by cationic polymerization in the present invention, because the monomer in the present invention must be a di-or poly-styryl compound having multiple functionalities, and only the styryl compound having di-or poly-functionalities can undergo a polymerization crosslinking reaction to form the organic porous polymer.
The specific surface area of the prepared material is 400-2000 m2The organic microporous polymer is prepared by selecting proper polymerization monomers and reaction conditions, wherein the specific surface area of the obtained polymer is larger as the number of the styryl functional groups in the styryl monomer is larger, and the specific surface area of the obtained polymer is larger as the polymerization time is longer in a certain period of time under the same other conditions.
The method is characterized in that the method is fully combined with the characteristics of cationic polymerization reaction, the reaction is rapid, the condition is mild, the synthesis requirement of the organic porous polymer is combined, the cationic polymerization reaction is skillfully applied to the preparation of the organic porous polymer, the preparation mechanism is explored by selecting proper polymerization monomers, the preparation process conditions are optimized, and finally the preparation method of the organic porous polymer with mild condition, high reaction speed, convenient operation and high production efficiency is obtained. The organic microporous polymer has controllable specific surface area and microporous structure, and can be widely applied to gas adsorption, separation, heterogeneous catalysis or photocatalytic water decomposition for hydrogen production.
