A mesoporous metal-organic framework of [Al(OH)(SDC)] (CYCU-3) (H2SDC = 4,4%26apos;-stilbenedicarboxylic acid) was synthesised by using Al(III) ions and H2SDC under solvothermal conditions. The structure forms 3D mesoporous frameworks in which the carboxylate oxygen on each terminus of the ligand forms octahedral AlO6 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 CO2 (2.83 mmol g(-1) CO2 at 273 K and 1 atm).
