Abstract

The invention discloses a porous organic polymer as well as a preparation method and application thereof, and efficient polymerization of various polymeric monomers in various coupling reactions is realized in one step by increasing the reaction temperature to be higher than the boiling point temperature of a solvent. The method is simple in equipment operation, short in synthesis period, high in yield, excellent in product character and easy to expand in reaction scale, and can be used for preparing a high-purity product under the conditions that any complex agents such as catalysts, cocatalysts and solubilizers do not need to be added and any degassing operation for removing water and oxygen does not need to be carried out. The specific surface area of the polymer can be increased by 20 times, the CO2 adsorption capacity is increased by 150% or above, the H2 adsorption capacity is increased to 4 wt% or above, and the mercury ion adsorption capacity in a water phase is increased to 1111 mg / g. The obtained product has wide application prospects in the aspects of adsorption catalysis, chemical sensing, gas storage, electrochemistry and the like.
