Description:: This dissertation examines the effects of phase transfers with thiol ligands on the optical properties of quantum dots (QDs) in water by investigating two systems: i) dihydrolipoic acid (DHLA)-capped PbS QDs and ii) thiolated DNA-capped core/shell CdSe/CdS QDs. QDs are bright, monodisperse, and tunable hydrophobic nanoparticles with high photoluminescence (PL)...

Description:: This thesis describes a series of fundamental studies that address the role of electrostatic interactions in modulating i) the permeability of the ligand shell of a colloidal quantum dot (QD) to an anionic redox probe; ii) the resulting yield of photoinduced electron exchange within the QD ‒ redox probe complex;...
