摘　　要：分别以萘和芘作为构筑单体,通过Friedel-Crafts烷基化反应合成2种低成本的稠环基超交联微孔聚合物(HCPs-1和HCPs-2),并利用红外光谱、固体核磁碳谱、扫描电镜、透射电镜、热重和氮气吸附解吸附等温线表征了该类聚合物的化学结构、微观结构和孔结构。碘蒸汽吸附测试表明,HCPs-1和HCPs-2的碘蒸汽饱和吸附量分别可以达到自身质量的204 wt%和250 wt%,同时也显示出高的循环稳定性(>10次)。Two kinds of low-cost fused ring-based hypercrosslinked polymers were synthesized by Friedel-Crafts alkylation reaction using naphthalene and pyrene as building monomers,respectively.The chemical structure,microstructure and pore structure of these polymers were characterized by Fourier transform infrared(FT-IR)spectroscopy,solid-state 13C NMR,scanning electron microscopy,transmission electron microscopy,thermogravimetric analysis and nitrogen adsorption and desorption isotherms.According to characterization of the iodine vapor adsorption,the saturated I2adsorption capacity of HCPs-1 and HCPs-2 can reach 204 wt%and 250 wt%of their own body weight respectively,and these polymers showed high recycle stability(>10 cycles).
