A copper coordination polymer based on bis(imidazole) and thiophenedicarboxylate for photocatalytic degradation of organic dyes under visible light irradiation

摘要

AbstractThe copper(II) coordination polymer [Cu2(bix)(sdc)2]n(1) was synthesized by the hydrothermal method (bix=1,4-bis(2-methyl-imidazol-1-ylmethyl)benzene, sdc=2,5-thiophenedicarboxylate). The copper(II) atom of1shows unsaturated square-pyramidal configuration.1exhibits the 2-fold interpenetrating three-dimensional pcu network based on the [Cu2(COO)4] dimers.1is an efficient and universal photocatalyst for the degradation of the organic dyes methylene blue (MB), rhodamine B (RhB) and methyl orange (MO) under visible light irradiation, and is very stable and can be reused.Graphical abstractA copper(II) coordination polymer showing 2-fold interpenetrating 3D pcu network based on the [Cu2(COO)4] dimers is an efficient and universal photocatalyst for the degradation of methylene blue, rhodamine B and methyl orange under visible light irradiation.Display OmittedHighlights?A 2-fold interpenetrating 3D pcu network based on the [Cu2(COO)4] dimers?The copper(II) atom shows unsaturated square-pyramidal configuration.?An efficient and universal photocatalyst under visible irradiation?The degradation of organic dyes (MB, RhB and MO)?The catalyst is very stable and can be reused.]]>
