Abstract Nanowires (NWs) and self-assemble nanostructures made of chalcogenide semiconductor nanocrystals (NCs) are of great interests to the fundamental studies and practical applications. In this study, we reported a seeded-mediated growth of AgInS2 NWs and their intriguing self-assembly nanostructures with fingerprint-like shape. The key to the formation and self-assembly of AgInS2 NWs was the presence of In-S species that was a type of molecular metal chalcogenide complexes, serving as specific inorganic ligands for the growth of NWs and cross-linker molecules for the self-assembly of fingerprint-like nanostructures. Systematic studies were carried out to investigate the reaction factors, including the thermodynamics, amount and type of In precursors, and 1-dodecanethiol usage, to the success of the desired products.
