Description
Summary:[Display omitted] •Compound 1 is reasonably characterized by luminescence spectrum and TG analysis etc.•Compound 1 possesses strong yellow-light emission with λmax = 595 nm.•Compound 1 exhibits a narrow band gap of 2.182 eV in semiconductor property. A novel tetranuclear Cu4I4 - organic amine cluster was synthesized, which was involved dimethylamine and cuprous iodide by hydrothermal, [C2H7N]4·Cu4I4 (1). The structure of compound 1 was determined by single crystal X-ray diffraction analysis and further characterized by elemental analysis, infrared spectroscopy, luminescence spectrum, powder X-ray diffraction, and thermogravimetric analysis. The result of solid-state luminescence spectrum testing of compound 1 displays strong yellow-light emission with λmax = 595 nm at room temperature, suggesting that compound 1 may be a good yellow light-emitting material. Specially, compound 1 exhibits a narrow band gap of 2.182 eV in semiconductor property and is chiefly contributed by inorganic Cu4I4 of [C2H7N]4·Cu4I4. These findings will contribute to an alternative pathway for exploring and developing novel fluorescence and semiconducting materials of the coordination compounds and related properties in other materials.
