A novel naphthalene diimide-based compound, designated as [Zn(BINDI)0.25·(C2H5NO)]n (1), has been successfully synthesized under solvothermal conditions, utilizing N, N′-bis(5-isophthalic acid) naphthalenediimide (H4BINDI) and Zn(NO3)2·6H2O as raw materials. Single crystal X-ray diffraction analysis revealed that compound 1 forms a 3D structure, with BINDI4− and C2H5NO− serving as organic ligands and Zn(II) as the center metal ion. Notably, upon exposure to a 300 W xenon lamp, compound 1 rapidly transitions from orange to dark blue within 5 s. Furthermore, as the duration of irradiation increases, 1 exhibits photocontrolled fluorescence properties. Additionally, it possesses the capability to detect ammonia vapor and triethylamine. The synthesized compound 1 not only has reversible photochromic properties, but also has visible color change to ammonia vapor and triethylamine, which can be used as one of the color-changing materials for detecting ammonia vapor and triethylamine.
