Abstract

A highly porous metal–organic framework Cu2(BBCDC) (BBCDC = 9,9′-([1,1′-[b with combining low line]iphenyl]-4,4′-diyl)[b with combining low line]is(9H-[c with combining low line]arbazole-3,6-[d with combining low line]i[c with combining low line]arboxylate) (DUT-49) with a specific surface area of 5476 m2 g?1, a pore volume of 2.91 cm3 g?1, a H2 excess uptake of 80 mg g?1 (77 K, 50 bar), a CO2 excess uptake of 2.01 g g?1 (298 K, 50 bar) and an exceptionally high excess methane storage capacity of 308 mg g?1 (298 K, 110 bar) was obtained using an extended tetratopic linker.
