摘要：Photo-stimulated Polymers have garnered significant attention for their potential applications ranging from optical memory to sensing. Herein, by changing coordination metal and the position of nitrogen atom in pyridine-based photo-stimulated ligand, we successfully synthesised a novel photo-stimulated copper-based MOF (Cu-MOF) using 9,10-bis(di(pyridine-3-yl)methylene)-9,10-dihydroanthracene as the photo-stimulated ligand. Structural analysis revealed a 3D porous architecture, offering a distinct advantage over previously reported 1D coordination polymer using similar photo-stimulated ligand. The Cu-MOF exhibited exceptional photoelectric properties, demonstrating potential as an anode material for lithium-ion batteries and a luminescent MnO4- sensor. Its electrochemical performance revealed high reversibility, with discharge capacities retaining stability under varying current densities. Additionally, the Cu-MOF displayed notable photo-stimulated behavior under UV light irradiation, enhancing its optical properties. Although the structure changes from 1D coordination polymer to 3D MOF, the photocyclized form (c-Cu MOF) still exhibited superior fluorescence quenching efficiency and sensitivity for MnO4- detection with Ksv (quenching constant) 5.24x105 M-1. This work highlights the utility of Cu-MOF as a multifunctional material for energy storage and environmental sensing applications.
