英文摘要Precisely modulating the structure of nanoparticles in a controlled manner is still a challenging and inspiring topic. Although the single or few-metal atom tailoring of gold nanoparticles has been reported, local structural replacement involving over three net metal atoms (module replacement, MR) has not been hitherto achieved. Herein, we report the synthesis of cyclohexanethiolated metal nanoclusters (NCs) Au-48(CHT)(26) and their MR by a so-called pseudo-anti-galvanic reaction (AGR) process. The MR product Au-37(CHT)(23) shares a similar Au-31(CHT)(12) unit with its predecessor Au48(CHT)26; however, it differs from its predecessor in the remaining section (Au-6(CHT)(11) vs. Au-16(CHT)(14)), as revealed by single-crystal X-ray crystallography (SCXC). Interestingly, the MR inhibits the photothermy but enhances the emission of Au-48(CHT)(26) NCs, which might endow the as-obtained NC better potential for bi(multiple)-functional application. The counter effects of the MR on the emission and photothermy indicate that photoluminescence and photothermy can be at least partly converted into each other, which has some important implications for the understanding of their interaction.
