RESUMO
We employed quantitative NMR spectroscopy and spectrophotometric absorbance titration to study a quantum dot X-type ligand exchange reaction. We find that the exchange is highly cooperative, where at low extents of exchange the change in free energy of the reaction, ΔGXC, is â¼11 kJ mol-1 while at higher extents of exchange ΔGXC saturates to â¼-4 kJ mol-1. A modified Fowler binding isotherm is developed to describe the reaction.
