Highlights

  • The unique properties of gold nanoparticles have been studied extensively.[1−4] The size and shape of the particles define their electronic and physical properties, whereas tuning the nature of the protecting organic layer gives a control of the solubility and chemical functionality of the particles.[1]

  • MeOH compositions yielding two different discrete products of a stable water-soluble cluster protected by p-mercaptobenzoic acid (pMBA)-thiol in milligram scale

  • The Au102(pMBA)[44] nanocluster was synthesized as a good reference point to compare synthetic trends, dispersity, and the size of the particles

Summary

INTRODUCTION

The unique properties of gold nanoparticles have been studied extensively.[1−4] The size and shape of the particles define their electronic and physical properties, whereas tuning the nature of the protecting organic layer gives a control of the solubility and chemical functionality of the particles.[1]. Experiments that require atomiclevel control are extremely difficult to carry out In this regard, monolayer-protected gold clusters (AuMPCs) are small (usually 200 gold atoms) water-soluble nanoclusters are still not yet fully understood.
