Four distinct coordination polymers (CPs) were successfully synthesized by altering solvent types and adjusting ligand concentrations, and their crystal structures were investigated. [Co(L)(FDCA)(H₂O)₂]·0.5H₂O (1) was synthesized as a 2D structure using Co(Ⅱ) as the metal source, methanol-water (4∶6, V/V) as the solvent, and specific concentrations of 2, 5-furandicarboxylic acid (H₂FDCA) and 1, 3, 5-triimidazole benzene (L). Adjusting to pure water and lowering the concentration of L yielded the 1D chain structure of [Co(HL)₂(H₂O)₂](FDCA)₂·6H₂O (2). Using Cu(Ⅱ) as the metal source, methanol/water (9∶1, V/V) as the solvent, and specific concentrations of L and H₂FDCA, the 1D chain structure of [Cu(L)(FDCA)(H₂O)]·2H₂O (3) was synthesized. Upon increasing the concentrations of L and H₂FDCA, and switching the solvent to pure water, the 1D chain structure of [Cu(HL)₂(H₂O)₂](FDCA)₂·6H₂O (4) was obtained. This shows that changing the solvent and ligand concentrations can affect the structural changes of CPs. In addition, the solid-state photoluminescence of CPs 1-4 at room temperature was studied, and their morphological changes were observed via scanning electron microscopy. Density functional theory calculations revealed that the negative charge concentrates on the O and N atoms of the ligand, facilitating ligand-metal ion coordination.
