A new microporous poly(Schiff base) (PSN-3) is constructed from 1,3,5,7-tetrakis(4-formylphenyl)adamantane and 1,3,5,7-tetrakis(4-aminophenyl)adamantane through an A4 -A4 ' reaction. The surface and internal morphologies of porous PSN-3 are examined by FE-SEM and HR-TEM. PSN-3 exhibits a BET surface area of 865 m(2) g(-1) with a major pore size around 0.6 nm. Moreover, PSN-3 can uptake 1.32 wt% H2 (77 K/1 bar), 13.6 wt% CO2 (273 K/1 bar), 80.5 wt% benzene, and 63.7 wt% cyclohexane (298 K/0.9 bar). The adsorption selectivities for CO2/N2, CO2/CH4, benzene/N2, and benzene/H2O are 88, 16, 267, and 19, respectively. The high adsorption capacities and selectivities for gases and vapors make PSN-3 a promising candidate for H2 storage, CO2 capture, and recovery of organic pollutants.
一种新型的微孔聚（席夫碱）（PSN-3）是由 1,3,5,7-四（4-醛基苯基）金刚烷和 1,3,5,7-四（4-氨基苯基）金刚烷通过 A4-A4'反应构建而成。多孔 PSN-3 的表面和内部形态通过 FE-SEM 和 HR-TEM 进行了检查。PSN-3 的 BET 比表面积为 865 m(2)g(-1)，主要孔径约为 0.6nm。此外，PSN-3 可以吸收 1.32wt%的 H2（77K/1bar），13.6wt%的 CO2（273K/1bar），80.5wt%的苯和 63.7wt%的环己烷（298K/0.9bar）。CO2/N2、CO2/CH4、苯/N2 和苯/H2O 的吸附选择性分别为 88、16、267 和 19。PSN-3 对气体和蒸气具有高吸附容量和选择性，使其成为储氢、CO2 捕集和有机污染物回收的有前途的候选材料。
