摘要
以3,3’-二硫代双(丙酰肼)和对苯二甲醛为组装基元,通过动态共价键采用界面组装法在常温常压下温和构筑了具有丰富CO吸附位点的介孔超分子聚合物PDP。利用动态共价键的动态可逆性,通过合成后修饰法将两种具有丰富氨基位点的化合物(聚乙烯亚胺及四乙烯五胺)组装于PDP结构上,构建了两种氨基功能化超分子聚合物材料PDPP和PDPT。相较于PDP,修饰后超分子聚合物CO吸附性能有了极大提升,PDPT在80℃下CO吸附量可达27.79cm~3/g。动态亚胺组装策略具有制备条件温和、结构功能可控等特性,为开发CO高吸附性能材料提供了全新思路。
A series of mesoporous supramolecular polymers(PDP) with abundant COadsorption sites were constructed through the interfacial assembly of 3,3’-dithiobenzide and p-benzaldehyde at room temperature and ambient pressure. Two kinds of amino-functionalized supramolecular polymers(PDPP and PDPT) were constructed by using imine exchange with polyethylene imine and tetraethylene pentamine. Compared to PDP, the COadsorption ability of the modified supramolecular polymers was greatly improved. The COadsorption capacity of PDPT can reach 27.79cm~3/g at 80℃. This dynamic imine assembly strategy provided a mild and controllable approach for the development of materials with high COadsorption performance.
