水溶性单层保护金团簇（MPCs）自1998年和1999年首次被报道合成以来，一直是许多研究小组研究的对象。一种配体形成保护金簇的单分子层的基本要求在一段时间前就已经建立了，但对于水溶性的mpc还没有这样的信息发表。我们鉴定了6个能够形成水溶性mpc的新配体，以及22个不能形成水溶性mpc的水溶性配体。我们的发现不仅有助于定义MPC形成的要求，而且有助于化学和生物学中应用的MPC的多样性。
Water-soluble monolayer-protected gold clusters (MPCs) have been an object of investigation by many research groups since their first syntheses were reported in 1998 and 1999. The basic requirements for a ligand to form a monolayer protecting a gold cluster were established some time ago for alkanethiolate MPCs, but there has been no such information published for water-soluble MPCs. We identify 6 new ligands capable of forming water-soluble MPCs, as well as 22 water-soluble ligands that fail to form MPCs. Our findings contribute not only to the definition of the requirements for MPC formation but also to the variety of MPCs available for applications in chemistry and biology.
