摘要
A mesoporous metal-organic framework of [Al(OH)(SDC)] (CYCU-3) (H 2 SDC = 4,4′-stilbenedicarboxylic acid) was synthesised by using Al(iii) ions and H 2 SDC under solvothermal conditions. The structure forms 3D mesoporous frameworks in which the carboxylate oxygen on each terminus of the ligand forms octahedral AlO 6 by corner-sharing. As verified by N 2 sorption measurements, the CYCU-3 exhibits the largest pore volume and open channels (3.0 nm) in the system of Al-MOFs reported to date. This mesoporous Al-MOF also displays highly porous properties and uptake capacities of H 2 (8.22 mmol g -1 at 77 K and 1 atm) and CO 2 (2.83 mmol g -1 CO 2 at 273 K and 1 atm). © 2013 The Royal Society of Chemistry.
