Abstract

A nanoparticle having one or more phosphonates or phosphinate ligands on their surface can be converted into nanoparticles with sulfonate ligands on their surface, by contacting the phosphonate-containing nanoparticles with a silylsulfonate reagent. Such nanoparticles are activated toward reactions with nucleophilic groups; thus the method provides activated nanoparticles, and methods of making and using them to produce modified nanoparticles.
