•A flexible MOF was constructed from a semi-rigid ligand.•Compound 1 exhibits effective adsorptions on MB and MO.•Compound 1 shows selective adsorption on MO from MB–MO mixture.
Removal of organic dyes has become an important issue from the biological and environmental standpoint. A metal–organic framework {[Zn2(L)(H2O)(DMA)]·DMA·H2O}n (1) (H4L = 9-(3,5-Dicarboxy-benzyl)-9H-carbazole-3,6-dicarboxylic acid, DMA = N,N′-dimethylacetamide) has been synthesized based on a multicarboxylate ligand through solvothermal reaction. Compound 1 has a 2D bilayered structure and exhibits effective adsorption on organic dyes. The adsorbing capacity of MB and MO are 139.6 mg/g and 116.9 mg/g, respectively. The selective adsorption properties on dyes were studied.
