Summary: The separation of propane/propylene mixtures is a challenging task in the petrochemical industry. Metal-organic frameworks (MOFs) have been identified as promising materials for this task due to their structural diversity and tunable pore dimensions. However, the low adsorption capacity and slow diffusion kinetics of MOFs have limited their efficiency. In this study, we report the fabrication of nano-sized MOF crystals for propane and propylene separation, which exhibit enhanced adsorption kinetics and improved adsorption capacity compared to micro-sized samples. This represents the highest efficiency among all reported MOF-based splitters for propane/propylene separation.

Summary: Here, we introduce a new subclass of copper(i) hybrid emitters that contain [CuxIy](z-) anions and Cu+ cations, separated in space by a Janus head ligand. When irradiated with UV light at 298 K, these unique Two-In-One hybrids exhibit a short-lived green TADF with near-unity quantum yield and strong solvatochromic effect. Furthermore, they demonstrate strong radioluminescence upon X-ray irradiation. These findings offer new possibilities for designing highly performant TADF materials.

Summary: A systematic study is conducted on the engineering of pore dimensions and pore functionality of fcu-type Y-based metal-organic frameworks (Y-MOFs) using different linear dicarboxylate linkers. The research demonstrates how slight changes in pore size and pore surface chemistry can affect the adsorption preference of C2H6, C2H4, and C2H2 by the MOFs, establishing clear relationships between pore size/pore surface polarity and C-2 adsorption selectivities. A specific compound, HIAM-326, shows remarkable preferential adsorption of C2H6 and C2H2 over C2H4, enabling the one-step purification of C2H4 from C2H6/C2H4/C2H2 ternary mixtures to obtain high purity C2H4 (99.9%+).
