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.

Abstract

The invention discloses a porphyrin group-containing conjugated microporous polymer and a preparation method thereof, The prepared conjugated microporous polymer has the inherent properties of large specific surface area, narrow pore size distribution, high physical and chemical stability, low skeleton density and the like, and shows a quite excellent adsorption capability on vapor molecules (likebenzene, methylbenzene, cyclohexane and vapor). Compared with the traditional adsorption material, the porphyrin group-containing conjugated microporous polymer facilitates the implementation of thereversible processes of capturing and releasing organic vapor through physical adsorption, and the vapor adsorbed by the polymer is capable of separating the vapor from a skeleton of the polymer through simple vacuum drying, so that the possibility of recycling materials is realized, and the recycling and reutilization of a solid adsorbent are facilitated. In addition, the method provided by the invention is simple, the cost of raw materials is low, and the porphyrin group-containing conjugated microporous polymer is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of adsorption materials, in particular to a porphyrin-based conjugated microporous polymer and a preparation method thereof. Background technique [0002] VOCs volatile organic compounds refer to organic compounds with a saturated vapor pressure greater than 133.32Pa at normal temperature and a boiling point below 50-260°C at normal pressure, or any organic solid or liquid that can volatilize at normal temperature and pressure. Volatile VOCs are very harmful. When the indoor VOCs concentration exceeds a certain concentration, people will feel headache, nausea, vomiting, limb weakness in a short time, and convulsions, coma, and memory loss in severe cases. In addition, VOCs can also harm the human liver, kidneys, brain and nervous system. VOCs are the formation of fine particulate matter (PM2.5), ozone (O 3 ) and other important precursors of secondary pollutants, which in turn cause atmospheric environmental problem...
