Abstract: Ultrasmall bimetallic nanoclusters (or bi-MNCs for short) have recently emerged as a new class of multi-functional nanoparticles (NPs) due to their ultrasmall size (typically below 2 nm), unique molecular-like properties (e.g., quantized charging and strong luminescence), controlled cluster compositions, and synergistic physicochemical properties. However, previous studies all focused on the one-step synthesis of hydrophobic thiolate-protected bi-MNCs, and there is no successful attempt in synthesizing water-soluble and atomically precise bi-MNCs, let alone engineering the surface functionalities of bi-MNC?s ligand shell. Moreover, synthesis of water-soluble and highly luminescent bi-MNCs is still a challenge, and the corresponding luminescence mechanism is also unclear. All such issues may constrict the advances of bi-MNCs in bioapplications where biocompatibility (e.g., water solubility), multi-functional ligand surface, and/or high luminescence are required. In this thesis, two novel synthetic strategies have been developed to synthesize water-soluble and atomically precise AuAg bi-MNCs with either tunable metallic compositions/surface functionalities or high luminescence.
