Synthesis, structure and photoluminescence of 3D lanthanide coordination polymers based on 2-(3,5-dicarboxybenzyloxy) benzoic acid

Eight novel three-dimensional lanthanide coordination polymers, [Ln(dcob)(DMF)(H2O)]n based on 2-(3,5-dicarboxybenzyloxy) benzoic acid, were prepared and characterized. 3, 4, 6 and 7 show luminescence of the trivalent lanthanides.

Description
Summary:Eight novel three-dimensional lanthanide coordination polymers, [Ln(dcob)(DMF)(H2O)]n based on 2-(3,5-dicarboxybenzyloxy) benzoic acid, were prepared and characterized. 3, 4, 6 and 7 show luminescence of the trivalent lanthanides. [Display omitted] •Eight lanthanide coordination polymers were prepared and characterized.•The structure shows a 3D framework with [Ln2(dcob)6(DMF)2(H2O)2] building block.•3, 4, 6 and 7 show luminescence of the trivalent lanthanides. A series of novel three-dimensional lanthanide coordination polymers with the building block [Ln2(dcob)6(DMF)2(H2O)2], [Ln(dcob)(DMF)(H2O)]n [Ln = Pr (1), Nd (2), Sm (3), Eu (4), Gd (5), Tb (6), Dy (7), Er (8), H3dcob = 2-(3,5-dicarboxybenzyloxy) benzoic acid, DMF = N,N-dimethylformamide], were prepared under hydrothermal conditions and characterized by X-ray single-crystal diffraction, infrared spectroscopy, elemental analysis and thermogravimetric analysis. 3, 4, 6 and 7 show luminescence of the trivalent lanthanides.
