摘　　要：共价有机框架材料(COF)得益于其具有低密度、高比表面积、固定的孔径和高的孔隙率等优点近年来被广泛应用于气体吸附或分离领域。然而,传统的溶剂热合成方法存在合成条件苛刻等不足,这限制了其在这方面的实际应用。文章利用简单的合成条件成功合成了两种具有良好结晶性的三嗪基富氮共价有机框架(TZ-COF)材料。对制得的TZ-COF的气体吸附性能进行了研究。结果表明,经热活化处理后的COF在101 kPa和273 K时对CO_(2)和N_(2)的吸附量分别为37 cm^(3)/g和1.4 cm^(3)/g,显示了其在气体捕集和选择性分离方面的应用潜力。Covalent organic framework(COF)has been widely used in the field of gas adsorption or separation in recent years because of its advantages of low density,high surface area,fixed pore size and high porosity.However,the traditional solvothermal synthesis methods have some shortcomings such as harsh synthesis conditions,which limits their practical application in this field.In this paper,two kinds of triazinyl nitrogen-rich covalent organic framework(TZ-COF)with good crystallinity were successfully synthesized under simple synthesis conditions.The gas adsorption properties of the prepared TZ-COF were studied.The results show that the adsorption capacity of COF after thermal activation for CO_(2)and N_(2)at 101kPa and 273K is 37 cm^(3)/g and 1.4 cm^(3)/g,respectively,indicating its potential application in gas trapping and selective separation.
