UNAM-1: a robust CuIand CuIIcontaining 3D-hydrogen-bonded framework with permanent porosity and reversible SO2sorption

Abstract: [CuIICuI12(HL)12]10− and [Me2NH2]+ ions assemble into a unique 3D hydrogen-bonded framework.

“…As depicted in Figure 1, Co‐URJC‐5 reached a SO 2 capture of 0.8 mmol g −1 at low pressure (0.05 bar) and a total SO 2 uptake of 1.48 mmol g −1 at 1 bar and 298 K (Figure 1). This total SO 2 uptake result is comparable to other porous materials with a similar BET surface area such as KAUST‐8, [18] FMOF‐2, [19] and UNAM‐1 [20] . Further, the stability after the SO 2 test was investigated by PXRD, where the results show a complete amorphization of the pristine crystalline phase (See ESI and Figure 2), accompanied by a color change from pink to deep‐purple before and after SO 2 adsorption experiments, respectively.…”

“…In 2019, Jancik and co-workers prepared permanent pores and functional hydrogen bond frameworks (termed as UNAM-1) through the charge-assisted H-bond between [Cu II Cu I 12 (HL) 12 ] 10and [Me 2 NH 2 ] + units, and reversibly adsorbed SO 2 (Figure 14a). 129 In the cubic crystal structure of UNAM-1, [Cu 13 (HL) 12 ] 10anions interact with DMAH cations (n/n:1:1) through hydrogen bonds (Figure 14b), and the multiple hydrogen bond interactions in the UNAM-1 structure yield a robust crystal.…”

“…Currently, the SO 2 adsorption with metal–organic frameworks (MOFs) experiences high interest. [ 11–27 ] Metal–organic frameworks are typically microporous metal‐ligand coordination networks with uniform porosity, low density, and high tunability through the organic linker, that is, the metal‐bridging ligand. [ 28 ] MOFs are actively studied in the role of adsorbents (particularly N 2 , H 2 , CO 2 , CH 4 , etc.)…”
