Embodiment 1

[0080] The synthesis of 2,4,5-tris(4-cyanophenyl)-1-hydroimidazoles (CMPs) monomers was carried out in an autoclave.

[0081] 1 molar part of 2,4,5-tris(4-bromophenyl)-1-hydroimidazole (0.533g), 3 molar parts of cuprous cyanide (0.268g), 1 molar equivalent of sodium carbonate (0.105g ) and refined 80 mole parts of DMF were added into the autoclave. Reaction at 150°C for 12h gave a dark purple solution. After cooling down to room temperature, filter with suction. Add concentrated ammonia water to the filtrate until the solution turns into a dark blue system. The solution was gradually added dropwise to an ice-water solution with a pH value of 9, stirred overnight and suction-filtered. The filter cake was dried and separated by column chromatography (dichloromethane:n-hexane, 1:3) to obtain a light yellow powdery solid (0.259g).

[0082] The obtained (CMPs) monomer 2,4,5-tris(4-cyanophenyl)-1-hydroimidazole (0.371g) and zinc chloride (0.408g) were mixed in a mortar and morta...

Embodiment 3

[0089] 1 molar part of 2,4,5-tris(4-bromophenyl)-1-methylimidazole (0.547g), 5 molar parts of cuprous cyanide (0.447g), 2 molar equivalents of sodium carbonate (0.210 g) and refined 90 mole parts of DMF were added to the autoclave. Reaction at 160°C for 10 h gave a dark purple solution. After cooling down to room temperature, filter with suction. Add concentrated ammonia water to the filtrate until the solution turns into a dark blue system. The solution was gradually added dropwise to an ice solution with a pH value of 8, stirred overnight and suction filtered. The filter cake was dried and separated by column chromatography (dichloromethane: n-hexane, 1:3) to obtain a light yellow powdery solid.

[0090] Zinc chloride is ground first, and then the obtained (CMPs) monomer 2,4,5-tris(4-cyanophenyl)-1-methylimidazole and zinc chloride are grinded at a molar ratio of 1:5 Grind in a bowl until powdered, and dry at 150°C overnight to remove water. The mixture was slowly added...

Abstract

The invention provides a rigid porous framework polymer with gas adsorption performance. A monomer is triaryl tricyano imidazole of R substitution, and R is hydrogen or alkyl with 1-5 carbon atoms. The invention provides a preparation method of the porous polymer and application of the porous framework polymer to the field such as oxygen reduction, hydrogen storage, adsorption and separation. The porous polymer materials have high nitrogen content and a micro-pore structure, the contact area between gas and the polymer is greatly increased, adsorption efficiency is improved, and the rigid porous framework polymer has good oxygen reduction performance under the carbon-forming condition and has good application prospects in the field such as oxygen reduction, hydrogen storage, adsorption and separation.

Description

technical field [0001] The invention belongs to the technical field of functional microporous polymers, and in particular relates to a preparation method of a rigid skeleton porous polymer material with gas adsorption performance, and uses of the polymer in the fields of oxygen reduction, hydrogen storage, adsorption, separation and the like. Background technique [0002] Due to global attention to the issue of greenhouse effect and carbon dioxide emission reduction, at the same time CO 2 It is also a potential carbon resource, making CO 2 Recycling, fixation, utilization and re-recycling have become a problem of great concern to countries all over the world. Coal-based thermal power plants emit CO 2 large households, if the CO in the flue gas can be 2 Recycling is a work that has both good social and economic benefits. After people's long-term exploration and research, the research shows that: the polyamino group in the molecular structure of the adsorption system is be...
