Pressure-Induced Luminescence Evolution Mediated by Phase Transition of a One-Dimensional Metal–Organic Chalcogenolate

and studied its optical property variations induced by hydrostatic pressure. An obvious dual emission in the compound could be observed during compression, which was aroused by the closer argentophilic interaction. Multiple in situ high-pressure characterizations combined with theoretical calculations were performed to investigate the evolution of its optical properties with structures. This study presents an interesting photophysical process of dual emission evolution, enriching the research on high-pressure applications in the field of metal-organic chalcogenolates (MOCs) and providing a reference for the design of next-generation MOCs with tailored optoelectronic functions.
