Synthesis of metal-adeninate frameworks with high separation capacity on C2/C1 hydrocarbons

By introducing isophthalic acid or 2,5-thiophenedicarboxylic acid to assemble with adenine and cadmium salt, two isostructural and anionic porous metal-organic frameworks (1 and 2) possessing the novel (4,8)-connected sqc topology are presented here. 1 shows permanent porosity with Langmuir surface area of 770.1 m2/g and exhibits high separation capacity on C2/C1 hydrocarbons.

Graphical abstractThe assembly between isophthalic acid, adenine ligands and Cd2+ ions leads to an anionic porous metal-organic frameworks, which shows permanent porosity and exhibits high C2/C1 hydrocarbons separation capacity.Figure optionsDownload full-size imageDownload as PowerPoint slide
