Abstract

We have realized a new porous metal-organic framework UTSA-80a with a elongated anthracene derivative as a linker, exhibiting higher pore volume of 1.03 cm3/g and gravimetric BET surface are of ca. 2280 m2/g than those of PCN-14. The volumetric methane storage capacity of UTSA-80a at 35 bar and 298 K is 192 cm3 (STP) cm-3, which is among those of the few porous MOFs whose storage capacities are higher than 190 cm3 (STP) cm-3 at 35 bar. Futhermore, its volumetric methane uptake reaches 233 cm3 (STP) cm-3 at room temperature and 65 bar, which achieves 88.6% of the new DOE volumetric target, if the packing density lost is ignored. This capacity is comparable to that of PCN-14. However, thanks to the lower methane uptake in UTSA-80a at 5 bar, it has much higher methane storage working capacity of 174 cm3 (STP) cm-3 than 157-160 cm3 (STP) cm-3 in PCN-14 (65 bar to 5 bar). This value is slightly lower than 190 cm3 (STP) cm-3 in HKUST-1, featuring it as a very promising material for methane storage for transport applications. Such exceptionally high working capacity is likely attributed to the elongated anthracene derivative as a linker within UTSA-80a, which adjusts the suitable pore sizes/cages and interactions with methane molecules to optimize the methane working capacity.
