Problems solved by technology

However, these two methods are relatively easy to prepare porphyrin ring molecules, but the yield is not high, and most of the synthetic polymers in the later stage require noble metal catalysts and high cost, which is not conducive to large-scale industrial production, thus limiting its practical application.
[0005] In recent years, organic porous materials containing carbazole have attracted much attention. As a very important nitrogen-containing heterocyclic compound, carbazole is relatively stable to heat, acid and alkali, and has a rigid main chain and a conjugated electron-rich system. , which is conducive to the formation of permanent porous materials, and can also enhance the interaction between the adsorbate and the adsorbent. Its nitrogen-containing structure can greatly improve the adsorption capacity of carbon dioxide acid gas, but the single unmodified and doped with any elements The adsorption capacity of carbazole porous materials is limited, which cannot meet the industrial demand for carbon dioxide adsorption conversion

[0063] Catalytic performance test of carbazole-containing quaternary phosphonium salts and metalloporphyrin polymer microporous materials:

[0064] The catalytic performance of CPBr-1 prepared in Example 1 and CPBr-2 prepared in Example 2 was tested. Different substituted propylene oxides were used as model compounds, and no external solvent was added under the reaction conditions of 2.5MPa and 90 °C, respectively. CPBr-1 and CPBr-2 are catalysts, and carbon dioxide and epoxide ring undergo an addition reaction to prepare cyclic carbonate. The specific chemical reaction formula is as follows:

Description

technical field [0001] The invention belongs to the field of organic porous polymer materials, in particular to a carbazole group-containing quaternary phosphonium salt and metalloporphyrin polymer microporous material and a preparation method and application thereof. Background technique [0002] Carbon dioxide is the most important greenhouse gas on the earth. Reducing carbon dioxide emissions is an important strategic issue for governments and scientific circles. At the same time, carbon dioxide is also the most widely distributed and abundant carbon resource on the earth, which means that humans can reduce carbon dioxide emissions. At the same time of carbon dioxide emission, it is converted into chemical products beneficial to human beings as carbon resources. Therefore, the study of carbon dioxide fixation and chemical conversion is of great significance. There are many ways to realize the conversion of carbon dioxide, mainly including catalytic activation, electrochem...
