Copper-based binary and ternary sulfides have attracted significant attention due to their excellent photophysical properties, making them highly promising for high-performance photovoltaic devices. This study focuses on the synthesis structural characterization of an air-stable binuclear Cu-pyrazinethiolate-phosphine complex, which serves as efficient single-source molecular precursor preparation CuS nanoplatelets. Furthermore, utility this complex a versatile copper-based sulfides, such CuInS2, Cu2SnS3, CuSbS2, has been demonstrated. A plausible mechanism facile formation these materials is proposed based presence disulfide (S–S) linkages in CuS. The crystal structure, phase purity, compositions nanoparticles were confirmed using powder X-ray diffraction (PXRD), photoelectron spectroscopy (XPS), energy-dispersive (EDS), area elemental mapping. Electron microscopic studies revealed two-dimensional (2D) nanoplatelet morphology with varied shapes sizes. Ultraviolet–visible (UV–vis) diffuse reflectance showed slight blue shift band gap compared bulk counterparts, can be attributed quantum confinement or surface lattice distortion effects. pristine found blue-shifted material. Prototype photoelectrochemical cells, fabricated nanoparticles, exhibit nice photocurrent generation along optimum photoswitching, poses suitable clean-energy applications.
