Abstract
Coordination polymers are multidimensional materials that can be utilized as photocatalytic materials for photodegradation of aromatic dyes. Herein, a new d10-configuration based Ag(I) supramolecular coordination polymer (CP) having formula {[Ag3(bib)2]·(H3L)2} (1) has been synthesized solvothermally using 1,3-bis(3,5-dicarboxylphenoxy)benzene (H4L) and 1,4-bis(1-imidazoly)benzene) (bib) ligands. The diimidazole ligand (bib) coordinates with Ag(I) where metal center adopts bi-coordinate linear-geometry to form cationic 1D coordinate chain, which is wrapped between 2D hydrogen-bonded organic plane to engender 3D suramolecular network. The CP is used as photocatalyst for the safe and sustainable decomposition of aromatic dyes. The percentage decomposition of dyes methylene orange (MO), Rhodamine B (Rh B), methylene blue (MB) and basic green (BG) are 5.44%, 61.38%, 63.75% and 83.31%, respectively under UV light irradiation. The plausible pathway using which the CP executed the decomposition of dyes proposed by theoretical calculations.
