摘要：

A porous cobalt-based metal-organic framework [CoL2-](n) (L = 5-(pyrimidin-5-yl) isophthalic acid) (termed NJFU-2), has been designed by self-assembling [Co-2(COO)(4)] paddlewheel SBUs and a novel trigonal hetero-functional ligand. Moreover, the activated sample NJFU-2a exhibits a moderate BET surface area of 1223 m(2) g(-1), large CO2 uptake (6.14 wt% at 0.15 bar and 298 K) and high selectivity for CO2 over CH4 and N-2 at room temperature, estimated by the Ideal Adsorbed Solution Theory (IAST).
