Abstract: In this research the ability of several ligands bounding to the surface of ZnS capped CdSe quantum dots (QDs) was studied. Different ligands for quantum dots functionalization was synthesized and characterized by ESI-MS, NMR and FT-IR techniques. The ligand exchange was carried out between synthesized ligands and trioctylphosphine oxide (TOPO) functionalized CdSe/ZnS quantum dots under different conditions. The functionalized CdSe/ZnS quantum dots was purified and characterized to ensure the successful bounding. Preliminary sensing studies were carried out using the functionalized quantum dots sensing peroxyl radicals and hydrosulfide anion.
