摘要
An imine-based nitrogen-rich covalent-organic framework(COF)was successfully synthesized using two tri-angular building units under solvothermal reaction condition.The gas adsorption properties of the obtained micro-porous nitrogen-rich COF were investigated.The results indicated that the activated COF material presented good up take capabilities of CO_(2) and CH_(4) at 61.2 and 43.4 cm^(3)·g^(−1)at 1 atm and 273 K,respectively,showing its applica-tion potential in selective gas capture and separation.
