Site-specific substitution in atomically precise carboranethiol-protected nanoclusters and concomitant changes in electronic properties

This study presents the synthesis and structural modification of a silver-based nanocluster [Ag₁₇(o₁-CBT)₁₂]^3- (Ag₁₇) by incorporating Au and Cu at specific sites, forming AuAg₁₆, Ag₁₃Cu₄, and AuAg₁₂Cu₄. These modifications systematically alter their structural, electronic, and optical properties, with Au stabilizing the core and Cu enhancing photoluminescence and prolonging excited-state lifetimes. The study demonstrates a tunable platform for nanocluster design, potentially useful for optoelectronics, catalysis, and sensor applications due to their stability and enhanced luminescence properties.
