Abstract

We discuss our recently developed method to selectively functionalize mixed ligand gold nanoparticles at two specific defect points in the ligand shell and to join the nanoparticles together into chains by placing reactive molecules at those two points. Here we use infrared spectroscopy to confirm that the process of functionalizing those defect points rapidly reaches equilibrium. In addition, we demonstrate the quantitative reproducibility of the chaining reaction, and we discuss the case in which we perform the same functionalization procedure on homoligand nanoparticles.
