ResumoA series of highly porous 4,8-connected isoreticular MOFs of the scu topology [Cu4(L1)(H2O)4]·20DEF, [Cu4(L2)(H2O)4]·16DMF·5H2O, and [Cu4(L3)(H2O)4]·14DMF (L1–L3 are (R)-1,1′-binaphthyl-derived octacarboxylate bridging ligands) were synthesized and characterized by single-crystal X-ray crystallography. Although the frameworks exhibit some distortion during the solvent removal process, the high-connectivity nature of the building blocks helps in stabilizing the frameworks, leading to high surface areas (SBET = 1189–2448 m2/g) and significant hydrogen uptake of up to 1.8 wt % (77 K, 1 atm).
