“…To work toward overcoming current and future challenges in modern society, porous materials have been intensively studied for potential applications in water purification, [1] water harvesting, [2] gas separation and storage, [3] drug delivery, [4] and sensing, [5] among others. In addition, heterogeneous catalysis using porous materials as catalysts, [6,7] or supports, [8,9] is and the possibility for linker-to-metal energy transfer (also known as the antenna effect in lanthanoid chemistry) to compete with photocatalytic performance.…”

The tetratopic linker, 1,3,6,8‐tetrakis(p‐benzoic acid)pyrene (H4TBAPy) along with rare‐earth (RE) ions is used for the synthesis of 9 isostructures of a metal–organic framework (MOF) with shp topology, named RE‐CU‐10 (RE = Y(III), Gd(III), Tb(III), Dy(III), Ho(III), Er(III), Tm(III), Yb(III), and Lu(III)). The synthesis of each RE‐CU‐10 analogue requires different reaction conditions to achieve phase pure products. Single crystal X‐ray diffraction indicates the presence of a RE9‐cluster in Y‐ to Tm‐CU‐10, while a RE11‐cluster is observed for Yb‐ and Lu‐CU‐10. The photooxidation performance of RE‐CU‐10 analogues is evaluated, observing competition between linker‐to‐metal energy transfer versus the generation of singlet oxygen. The singlet oxygen produced is used to detoxify a mustard gas simulant 2‐chloroethylethyl sulfide, with half‐lives ranging from 4.0 to 5.8 min, some of the fastest reported to date using UV‐irradiation and < 1 mol% catalyst, in methanol under O2 saturation.

“…Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) of RE-CU-10 samples shows the expected symmetric (~1420 cm -1 ) and asymmetric stretching (~1530 and ~1600 cm -1 ) of the carboxylates, stretching of terminal carboxylic acids on the crystal surface (2500-3500 cm -1 ), aromatic C-H stretching at ~3060 cm -1 and O-H stretching at ~3650 cm -1 (Figure S16) which correspond to hydroxyl groups in the RE cluster node. The broad character of the O-H stretch suggests hydrogen bonding with guest molecules such as 2-FBA, HOAc and/or DMF which are observed by 1 H-NMR spectroscopy of digested RE-CU-10 samples (Figure S17-S24). Owing to the rapid relaxation of the 1 H nuclei due to the presence of Gd(III), a 1 H-NMR spectrum of Gd-CU-10 could not be collected.…”

The rectangular tetratopic linker, 1,3,6,8-tetrakis(p-benzoic acid)pyrene (H4TBAPy) along with rare-earth (RE) ions is used for the synthesis of 9 isostructures of a metal–organic framework (MOF) with shp topology, named RE-CU-10 (RE = Y(III), Gd(III), Tb(III), Dy(III), Ho(III), Er(III), Tm(III), Yb(III) and Lu(III)). The synthesis of each RE-CU-10 analogue requires different reaction conditions to achieve high quality phase pure products. Single crystal X-ray diffraction indicates the presence of a RE9-cluster in Y- to Tm-CU-10, while a unique RE11-cluster is observed for Yb- and Lu-CU-10. The photooxi-dation performance of the reported RE-CU-10 analogues is evaluated, giving insight into the competitive process of ligand-to-metal energy transfer versus the generation of singlet oxygen by RE-CU-10. The singlet oxygen produced is used to detoxify a mustard gas simulant 2-chloroethylethyl sulfide (2-CEES) to 2-chloroethyl ethyl sulfoxide (2-CEESO), with half-lives ranging from 4.0 to 5.8 min, some of the fastest reported to date using UV-irradiation and < 1 mol% catalyst, in methanol under O2 saturation.
