A novel anion-pillared metal-organic framework for highly efficient separation of acetylene from ethylene and carbon dioxide

Separation of acetylene (C2H2) from ethylene (C2H4) and carbon dioxide (CO2) is of great importance in the petrochemical industry but remains a daunting challenge due to their very similar sizes and physical properties. Although a number of porous materials have been developed as promising adsorbents for either C2H2/C2H4or C2H2/CO2separation, few materials exhibit simultaneously high selectivities for both gas mixtures. Herein, we report the use of a four-connected N-donor organic linker to construct a novel water-stable SIFSIX-type material, [Cu(TPB)SiF6]n(termed ZJU-280, TPB = 1,2,4,5-tetra(pyridin-4-yl)benzene). This material features suitable rhombic pores and functional surfaces to interact optimally with C2H2molecules, affording high C2H2capture capacity and simultaneously high C2H2/CO2(18.1) and C2H2/C2H4(44.5) selectivities under ambient conditions. Theoretical calculations indicate that the suitable rhombic pores and functional sites can provide a multipoint binding environment to not only preferentially interact with C2H2but also enable the dense packing of C2H2molecules within the framework. Actual breakthrough experiments demonstrate that ZJU-280a can efficiently separate C2H2from C2H2/CO2(50/50, v/v) and C2H2/C2H4(1/99 and 50/50) mixtures, respectively.

Structural competition between π...π interactions and halogen bonds: A crystallographic study

1,3-Diiodotetrafluorobenzene and 1,3,5-trifluoro-2,4,6-triiodobenzene form co-crystals with 4,4′,6,6′-tetramethyl-2,2′-bipyrimidine, 1,2,4,5-tetra(3-pyridyl)benzene and 1,2,4,5-tetra(4-pyridyl)benzene in which the structural competition between π...π interactions and halogen bonds is directly observed. It is found that the strong C-I...N halogen bond competes successfully with the π...π interaction between two 1,3-diiodotetrafluorobenzene molecules while the π...π interaction between two 1,3,5-trifluoro-2,4,6-triiodobenzene molecules can successfully compete with the strong C-I...N halogen bond. Quantum chemical calculations explain the structural competition well.
