The efficient removal of organic pollutants from wastewater is a hot research topic due to its ecological and environmental importance. Herein, by using the ligand-truncation and functionalization strategy, a Cu(II)-based 3D metal-organic framework (MOF), [Cu2(L1)∙5DMF]n (1) (H4L1 = 3,5-di(3,5-dicarboxyphenyl)nitrobenzene), has been designed, prepared and characterized. The single crystal X-ray diffraction results indicates that MOF 1 possess a 3D framework with 1D hexangular channels. The MOF 1 has been used as photocatalyst for the photodegradation of organic dyes viz. methyl violet (MV) and Rhodamine B (Rh B). The photocatalytic results indicated that 1 offered better photocatalysis towards the photodegradation of MV in comparison to Rh B. The probable mechanism for the photocatalytic activity of 1 has been addressed using density of states (DOS) and partial DOS calculations. A Cu(II) based 3D MOF with 1D hexangular channels synthesized and its application as photocatalyst to degrade organic dyes explored. [Display omitted] •The Cu(II)-based 3D MOF with 1D hexangular channels synthesized.•The MOF had been used as photocatalyst for the degradation of organic dyes.•MOF displays good recyclability to be used as a photocatalyst.•The DOS calculations have been used to assess the photocatalytic mechanism.
