Metal-doped porous organic polymers often display unique properties for applications in gas uptake owing to the incorporation of the metal elements in the polymer networks. In this study, a series of novel ferrocene-based hypercrosslinked polymers were prepared by phenolic polycondensation (Fc-PR-HCPs). To generate the hypercrosslinked polymers, 1,1′-ferrocenedicarboxaldehyde (Fc(CHO)2) and bisphenol A (BPA) were used as the building blocks. The maximum value of BET and micropore surface area is determined to be 1111.4 and 487.4 m2/g for Fc-PR-HCP3. A significant H2 adsorption capacity of 3.11 wt% was achieved for Fc-PR-HCP3 at 77 K/1.0 bar, which was noted to be higher than the porous organic polymers with even higher BET surface area value. The high micropore surface area value and the adsorption sites (aromatic rings and metal ion-active sites) provided by two building blocks were used to explain the significant H2 adsorption capacity successfully. Overall, the findings from this study indicate that Fc-PR-HCPs highlighted prospective applications in the field of H2 capture.

基于二茂铁的超交联聚合物，源自酚醛缩聚反应，具有意想不到的 H2 吸附能力

由于聚合物网络中掺杂了金属元素，金属掺杂多孔有机聚合物通常表现出独特的气体吸收应用性能。在本研究中，通过酚醛缩聚法（Fc-PR-HCPs）制备了一系列新型二茂铁基超交联聚合物。为了生成超交联聚合物，使用 1,1′-二二铁甲醛（Fc（CHO）2）和双酚 A （BPA）作为构建单元。对于 Fc-PR-HCP3，BET 和微孔表面积的最大值确定为 1111.4 和 487.4 m2/g。在 77 K/1.0 bar 下，Fc-PR-HCP3 的 H2 吸附容量达到 3.11 wt%，高于具有更高 BET 表面积值的多孔有机聚合物。高微孔表面积值和两个构建单元提供的吸附位点（芳香环和金属离子活性位点）被用来成功解释显着的 H2 吸附能力。总体而言，本研究的结果表明，Fc-PR-HCPs 突出了 H2 捕获领域的潜在应用。
