The desolvated (3,24)-connected metal–organic framework (MOF) material, MFM-160a, [Cu3(L)(H2O)3] [H6L = 1,3,5-triazine-2,4,6-tris(aminophenyl-4-isophthalic acid)], exhibits excellent high-pressure uptake of CO2 (110 wt% at 20 bar, 298 K) and highly selective separation C2 hydrocarbons from CH4 1 bar pressure. Henry’s law selectivities 79:1 for C2H2:CH4 70:1 C2H4:CH4 K are observed, consistent w...

Wholly aromatic thermotropic liquid crystalline polymers (TLCPs) are an important class of high-performance materials, which offer a combination of excellent thermal and mechanical properties. TLCPs can be processed from the nematic melt into high-modulus fibers, films and molded articles. However, despite their all-aromatic composition, main-chain TLCPs exhibit low glass transition temperature...

A convenient, fast and selective water analysis method is highly desirable in industrial and detection processes. Here a robust microporous Zn-MOF (metal-organic framework, Zn(hpi2cf)(DMF)(H2O)) is assembled from a dual-emissive H2hpi2cf (5-(2-(5-fluoro-2-hydroxyphenyl)-4,5-bis(4-fluorophenyl)-1H-imidazol-1-yl)isophthalic acid) ligand that exhibits characteristic excited state intramolecular pr...

In the title proton-transfer organic salt, C5H6.3N5 (+)·C8H4.7O4 (-)·C3H7NO, the adeninium moiety is protonated at the N atom in the 1-position of the 6-amino-7H-purin-1-ium (adeninium) cation. In the solid state, the second acidic proton of isophthalic acid is partially transferred to the imidazole N atom of the adeninium cation [refined O-H versus N-H ratio = 0.70 (11):0.30 (11)]. Through the...

Two new Co(II) coordination polymers with a pyridinedicarboxylate ligand, {[Co(L)(H(2)O)]·H(2)O}(n) (1) and [Co(3)(HCOO)(2)(L)(2)(H(2)O)(2)](n) (2) (H(2)L = 5-(pyridin-4-yl)isophthalic acid), have been synthesized and structurally characterized by elemental analysis, IR, XRPD, and single-crystal X-ray diffraction. Structure analyses show that complex 1 has a two-dimensional (2D) double-layered ...
