Abstract: Three new supramolecular polymers based on Cu(X) (X = Br, I, SCN) and BPMB·2Br (BLMB = 1, 4-bis [(4-picoline)-N-methylene] benzene) have been synthesized via the self-assembly reaction in solution. 1–3 were characterized by X-ray crystal structure, TG, IR, elemental analysis UV-Vis, and XRD. These compounds exhibit mononuclear, tetranuclear cubane-like clusteric oligomer and 1D chain structure, respectively. We investigated the photocatalytic degradation properties and the optical band gap of them. Moreover, fluorescence spectrum indicates that they are probe for sensing Fe3+, resulting in Fe (III)-selective fluorescence quenching in water even in the presence of other metal ions.
