摘要： As demonstrated herein, the ligand exchange chemistry of phosphine- stabilized Au11 clusters with ?-functionalized thiols is a powerful synthetic method that provides convenient access to a diverse family of functionalized Au11 clusters. The general nature of the presented ligand exchange approach, in combination with the ease preparation, makes this approach of broad utility. The approach is general and shows the high tolerance for a wide variety of functional groups. Mechanistic studies provided conclusive evidence that the Aup core of the precursor particle remains intact during ligand exchange and showed that the ligand exchange of these particles follows a different pathway than for ligand exchanges of larger gold nanoparticles such as "Au1Oi(PPh3)2iCl5". Optical studies of the products show a strong dependence on the nature of the stabilizing thiol ligands.
摘要翻译：如本文所证明的，膦稳定化的Au11簇与β-官能化硫醇的配体交换化学是一种功能强大的合成方法，其提供了对功能化的Au11簇的多种家族的方便访问。所提出的配体交换方法的一般性质，与易于制备相结合，使得这种广泛用途的方法。该方法是一般性的，并且显示出对各种功能组的高度容忍度。机理研究提供了确切的证据，表明前体颗粒的Aup核心在配体交换期间保持完整，并且表明这些颗粒的配体交换遵循与比较大的金纳米颗粒如“Au 101（PPh 3）2iCl 5”的配体交换不同的途径。产物的光学研究显示强烈依赖于稳定巯基配体的性质。
