Quantitative 1 H NMR measurements were taken to determine the number of bound indium carboxylate ligands per quantum dot as a function of moles of zinc chloride to moles of indium phosphide quantum dots, (Figure ). Full example NMR spectra and fitting methods can be found in the Supporting Information (Figures ). As the titration progresses, the number of free indium tri-carboxylate ligands until the reaction end point reached in isothermal titration calorimetry measurements. One interesting observation to note is the somewhat high variability of ligand coverage per quantum dot as observed by 1 H NMR (Table ). The quantum dots did not exhibit a clear trend of ligand coverage with nanocrystal size. Similarly sized quantum dots with stearate and myristate ligand shells varied in their ligand coverage as well. This variability illustrates an important feature of quantum dot syntheses: synthetic products may be inconsistent.
