摘要
以含三苯胺结构多元胺和醛基化合物为单体,采用超交联反应聚合得到含三苯胺和二氮杂萘酮结构的多孔有机聚合物,采用红外、核磁和气体吸附仪表征其结构,研究了其结构与碘吸附性能的关系。结果表明,该类聚合物具有多级孔结构,以微孔和介孔结构为主,比表面积(BET模型)为360~766m^2/g,对碘蒸气的吸附质量分数可达273.79%,20min吸附的碘蒸气为136.36%~146.32%(质量分数)。
Porous organic polymers containing triphenylamine and phthalazone structures were synthesized by the crosslinking polymerization of multi-amine monomers and aldehydes.FT-IR,NMR and the gas sorption analyzer were utilized to characterize the structures of polymers.Meanwhile,the relationship between structures and iodine adsorption properties was studied.The results indicate that the polymers have hierarchical porous structure(mainly containing micropores and mesopores)and high specific surface area(BET model,766 m^2/g).The final iodine vapor adsorption of the polymers is as high as 273.79%and they could adsorb iodine of 146.32%within 20 min.
