Abstract

Solvothermal reactions of Cu(NO 3 ) 2 with azoxybenzene-3,3′,5,5′-tetracarboxylic acid (H 4 aobtc) or trans -stilbene-3,3′,5,5′-tetracarboxylic acid (H 4 sbtc) give rise to two isostructural microporous metal−organic frameworks, Cu 2 (abtc)(H 2 O) 2 ·3DMA (PCN-10, abtc = azobenzene-3,3′,5,5′-tetracarboxylate) and Cu 2 (sbtc)(H 2 O) 2 ·3DMA (PCN-11, sbtc = trans -stilbene-3,3′,5,5′-tetracarboxylate), respectively. Both PCN-10 and PCN-11 possess significant enduring porosity with Langmuir surface areas of 1779 and 2442 m 2 /g (corresponding to BET surface areas of 1407 or 1931 m 2 /g, respectively) and contain nanoscopic cages and coordinatively unsaturated metal centers. At 77 K, 760 Torr, the excess gravimetric (volumetric) hydrogen uptake of PCN-10 is 2.34 wt % (18.0 g/L) and that of PCN-11 can reach 2.55 wt % (19.1 g/L). Gas-adsorption studies also suggest that MOFs containing C═C double bonds are more favorable than those with N═N double bond in retaining enduring porosity after thermal activation, although N═N has slightly higher H 2 affinity. The excess gravimetric (volumetric) adsorption at 77 K saturates around 20 atm and reaches values of 4.33% (33.2 g/L) and 5.05% (37.8 g/L) for PCN-10 and PCN-11, respectively. In addition to its appreciable hydrogen uptake, PCN-11 has an excess methane uptake of 171 cm 3 (STP)/cm 3 at 298 K and 35 bar, approaching the DOE target of 180 v(STP)/v for methane storage at ambient temperature. Thus, PCN-11 represents one of the few materials that is applicable to both hydrogen and methane storage applications.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
