Abstract
In situ generation and stabilization of colloidal semiconductors in synthetic single-bilayer surfactant and polymerized surfactant vesicles are described. Vesicles provide sites for the formation of controllable-sized semiconductors; shift the equilibrium between nucleation and particle growth in favor of the former; effect band gaps, reduction and oxidation potentials; and influence electron transfer to and from donors and acceptors located on, or in close proximity to, the semiconductor. A brief description of the properties of surfactant vesicles and polymerized surfactant vesicles is provided. Quantum size effects in, and water photoreduction by, vesicle-stabilized, colloidal CdS are then discussed in some detail.
