我们报告了固有的微孔性(network-PIMs)网络聚合物的合成和性质,该聚合物来自具有连接至其桥头位置的烷基的三茂基单体。可以通过烷基链的长度和支链来控制气体的吸附,从而使材料的表观BET表面积可以在618-1760 m 2 g -1的范围内进行调整。。较短的(例如甲基)或支链的(例如异丙基)烷基链提供了最大的微孔性,而较长的烷基链似乎阻止了由刚性有机骨架产生的微孔。与其他PIM相比,增强的微孔性源自骨架的大分子形状,这是由三萜烯单元决定的,这有助于减少刚性骨架的延伸平面支柱之间的分子间接触,从而降低了填充在骨架内的效率。坚硬的。对于具有低或中等压力(在1 bar / 77K下为1.83质量%;在18 bar / 77 K下为3.4质量%)的纯有机材料,具有甲基或异丙基取代基的三茂基PIM的氢吸附能力是最高的。 )。
