This review provides a unified perspective on rod-like Au<sub>25</sub> nanoclusters, encompassing key characterization methods, ligand engineering strategies, heteroatom doping effects, and future research directions. Current studies reveal that ligand engineering primarily governs low-energy electronic transitions, near-infrared emission, chiroptical responses, and substrate-activation pathways by modulating shell rigidity, local asymmetry, and site exposure. In contrast, heterometal doping regulates photoluminescence behavior, energy-transfer processes, and photocatalytic and electrocatalytic performance through site-selective substitution, thereby reshaping frontier-orbital distributions, energy-level alignment, and interfacial electronic structure. Future progress will require advances in predictive synthesis, site-selective doping, operando characterization, and the integrated design of ligand engineering and heterometal doping within a single cluster platform.
