This thesis examines the surface chemistry of the CdTe quantum dots by introducing a two unique classes of nitroxide radicals into its chemical environment. Nitronyl and imino nitroxide radicals were strategically chosen as the nitroxide radicals for this study for two reasons. One, each radical has its own unique electronic structure. Two, each radical is known to chemically stable. CdTe quantum dot system was chosen because of the ease of its synthesis and also their post synthetic flexibility. The synthesis and characterization CdTe quantum dots as well as nitronyl nitroxide and imino nitroxide radicals will be discussed. The chemical interactions of both radicals with the surfaces of the CdTe quantum dots will be also be examined. This includes their potential use as radical ligands for studying the potential binding interactions of both radicals onto the surfaces of the quantum dot. In addition to this, their chemical liability towards the quantum dot and the ligands surrounding the quantum structure will also be discussed. In both studies will be probed with electron paramagnetic resonant spectroscopy.
