摘要
Four Mn-II-based MIL-53 single crystals were prepared using Four neutral pyridine N-oxides as bridging Q-ligands. In the case of 4,4'-bipridine-N,N'-dioxide (BPNO), the infinite manganese oxide chains were Further interconnected by BPNO besides BDC, which allows I D channels to be accessible for guest molecules. The liquid-phase adsorption and separation of C6-C8 aromatics using the evacuated compound as an absorbent were investigated via crystal-to-crystal trails formations. Both structural evolution of the compounds and selectivity of C6-C7 aromatics of one evacuated compound Could be attributed to noncovalent interactions, especially pi-pi interaction.
