文摘

Two new three-dimensional porous Zn(II)-based metal鈥搊rganic frameworks, containing azine-functionalized pores, have been readily and quickly isolated via mechanosynthesis, by using a nonlinear dicarboxylate and linear N-donor ligands. The use of nonfunctionalized and methyl-functionalized N-donor ligands has led to the formation of frameworks with different topologies and metal鈥搇igand connectivities and therefore different pore sizes and accessible volumes. Despite this, both metal鈥搊rganic frameworks (MOFs) possess comparable BET surface areas and CO₂ uptakes at 273 and 298 K at 1 bar. The network with narrow and interconnected pores in three dimensions shows greater affinity for CO₂ compared to the network with one-dimensional and relatively large pores鈥攁ttributable to the more effective interactions with the azine groups.
