Quantifying Ligand Exchange on InP Using an Atomically Precise Cluster Platform
TL;DR: The surface properties of colloidal InP clusters and quantum dots are characterized by examining the binding of traditional stabilizing ligands including carboxylates, phosphonates, and thiolates by using the In37P20X51 cluster species as an ideally monodisperse and well-defined starting scaffold and showing that 1:1 metathesis-type binding models are insufficient to fully describe the surface dynamics.
