More Information:

Nanoparticle devices promise to provide a systematic and modular approach to creating supramolecular assemblies of linked nanoparticles that function as charge transfer elements. I will describe recent work in which we explore how to engineer nanoparticle/nanoparticle interfaces and nanoparticle/conjugated polymer interfaces to enhance charge separation and inhibit charge recombination. Particular foci of our effort are aimed at understanding the importance of energy-level gradients, built-in electrostatic potentials, and symmetry/chirality properties.
