Assembly of a novel Ag(I) supramolecular architecture constructed from flexible ligand containing asymmetrical tricarboxylate

A novel Ag(I) compound [Ag(H2cpop)(bpy)]n (1) (H3cpop = 4-(4-carboxyphenoxy) phthalic acid, bpy = 4,4′-bipyridine), has been hydrothermally synthesized and structurally characterized. H3cpop came from the in situ decarboxylation of H4odp (H4odp = 4,4′-oxydiphthalic acid) in the hydrothermal reactions. Compound 1 was obtained from the self-assembly of Ag(I) salt with bpy and H4odp ligands to form a 1D chain bearing hooks with carboxyl groups. The two chains are recognized each other to generate molecular zipper structure by hydrogen bonding interaction between the bearing carboxyl groups. Compound 1 is stable in air, and show intense photoluminescence at room temperature.

[Ag(H2cpop)(bpy)]n (1) was hydrothermal synthesized and characterized. H3cpop comes from the in situ decarboxylation of H4odp in the hydrothermal reactions. Compound 1 shows 1D chain bearing hooks with carboxyl groups. The two chains are recognized each other to form zipper structure by hydrogen bonding interaction between the bearing carboxyl groups. The double chain structure is further interconnected by supramolecular interactions resulted a 3D supramolecular architecture.Figure optionsDownload as PowerPoint slide
