Quantum dots are attractive potential components for next generation technologies such as light emitting diodes, sensors, and photovoltaic cells due to their unique and tunable electro-optical properties. The effective integration of quantum dots into devices requires a stable dispersion or self-assembly of the quantum dots in the solid-state. Such dispersions or assemblies are dictated by the interactions between the ligand environment of the quantum dots and the chosen polymer matrix. This thesis will highlight key contributions to the area of tailored cadmium selenide nanocrystals through the use of novel, functionalized ligands. This includes the utilization of ring-opening metathesis polymerization (ROMP), reversible addition fragmentation chain-transfer (RAFT) polymerization, and metal mediated couplings to control the polymer composition and molecular weight in radial polymerizations from CdSe nanocrystals. CdSe quantum dots were also found to assembly at the interface of immiscible fluids, and through appropriately functionalization these assemblies were effectively cross-linked. The key fording in this work is the retention of the inherent quantum dot fluorescence following these polymerization methods.
