ABSTRACT
An amide-containing adenine-mediated rod metal-organic framework was solvothermally constructed by means of mixed-linker approach, which exhibits both C2H2 and C2H6 selective adsorption, resulting in one-step ethylene purification from a ternary mixture of C2H2/C2H4/C2H6 as proved by not only IAST prediction, but also column breakthrough experiments. -

ABSTRACT
The switchable molecular dynamics and order-disorder transformation of (i-PrNHMe2)+ cation embedded in a deformable {[Ni(NCS)6]4–} supramolecular framework accompanied by solid-state structural phase transitions are reported, finding the confined swinging or flipping of the cation as a whole is assisted by a synergistic change of its torsion angle.

ABSTRACT
Ni(ina)(bdc)0.5 has tetrahedral and trigonal-pyramidal cages for respectively capturing SF6 and N2, which reduces their competition for adsorption sites. The smaller window diameter of Ni(3-min)(bdc)0.5 is more conducive to forming stronger hostguest interactions of gas molecules and frames, which improves the selectivity and adsorption capacity of SF6. -

SOD activity, Catecholase activity, Cytotoxicity
ABSTRACT
Two copper(II) complexes with excellent SOD and catecholase activities are obtained by solvothermal reaction. The SOD activity and catecholase activity are directly affected by the coordination configuration of the central metal atom and the ability of the complex to accept electrons. It has good application potential in the clinical biomedical field in the future. -
