The nitrogen‐containing conjugated microporous polymers (NCMPs) are synthesized by palladium‐catalyzed Sonogashira–Hagihara crosscoupling condensation of 1,3,5‐triethynylbenzene and bis(4‐bromophenyl)amine. The resulting NCMP sample exhibits good chemical and thermal stability due to its rigid structure. The choice of reaction solvents has a major influence on the porosity of NCMPs. The high specific surface areas of 945 m 2 g −1 and 593 m 2 g −1 are obtained for NCMP‐I and NCMP‐III using toluene and 1,4‐dioxane as solvent. Taking advantage of the good porous characters and the chemistry of amine groups, the NCMP‐I and NCMP‐III show superior adsorption performance for CO 2 and metal ions. The adsorption capacity of NCMP‐I and NCMP‐III for Ni (II) is measured to be 384 mg g −1 and 362 mg g −1 . Given these excellent metal ions uptake, ease of preparation, and good physiochemical stability, the as‐synthesized NCMP samples show great potential in CO 2 uptake and removal of metal ions.
