p-Terpheny1-2,2 '',5 '',5 '''-tetracarboxylate acid based bifunctional 1D Zinc(II) metal-organic platform for luminescent sensing and gas adsorption

摘要

Based on the mixed ligands strategy of p-terpheny1-2,2 '',5 '',5'"-tetracarboxylate acid (H(4)tptc) and 1,10-phenanthroline (phen), a novel Zinc(II) coordination polymer, {[Zn(tptc)(0.5)(phen))-dioxane}(n) (1), has been constructed. Structural analysis revealed that complex 1 is a 1D polymeric chains based architecture, with the porosity is 25.3% after remove the solvents. The gas adsorptions reveal that complex 1 displaying high CO2 selective absorption over N-2 and CH4. Besides, the luminescent sensing investigation indicating complex 1 exhibiting highly luminescent sensitive sensing of Cr(VI) anions in aqueous solution.
