摘要
随着人类社会的进步和工业的发展,化石燃料大量使用引起的二氧化碳(CO_2)过量排放造成全球变暖已经成为了一个严重威胁人类生存和发展的环境问题~~[1]。因此,发展高效吸附CO_2的材料成为全世界材料科学家们关注的研究热点。其中,杯芳烃以其可调控大小的空腔结构,优秀的热稳定性以及二氧化碳吸附性能而备受关注~~[2]。在前期研究中,我们发现硝基的引入能大大增强材料对CO_2的吸附性能~~[3]。因此,本论文设计合成了四硝基化氮杂杯~~[4]芳烃1和2,并研究了其对CO_2的吸附性能(图1),发现不含分子内氢键的2具有较高CO_2吸附量。该结果为进一步基于氮杂杯芳烃发展硝基功能化的有机多孔材料奠定了基础。
The extensive use of fossil fuel with industrial development has caused global warming,which has proved to be a big problem to the life of our human being.Therefore,it is very urgent to develop highly efficient CO_2 adsorption materials,which has also become a hot research topic.The calixarene is found to have the potential of adsorbing CO_2 draws much attention,owing to it's controllability of the cavity size and excellent thermal stability.In the preliminary study,we found that the introduction of nitro group to the backbone of porous polymer can greatly enhance the CO_2 Adsorption.In this presentation,tetranitro-tetraazacarlix[4]arene 1 and 2 are designed and synthesized,and their CO_2 adsorption was investigated(Fig.1).The destruction of intramolecular hydrogen bond by N-allylation of 1 contributes to its CO_2 adsorption positively.This work will give insight to the further development of nitro-functionalized azacarlix[4]arene-based organic porous materials.
