| Mixed Monolayer Protected Gold Clusters (MMPCs) are nanoscopic entities that provide a building block for microscale constructs. Functionalized MMPCs also provide a scaffold for the attachment of molecular devices, providing a platform for the construction of functional nanoscopic systems. To this end, MMPCs containing redox-active and aromatic pi-stacking functionalities have been synthesized. Redox modulation of these functionalities is observed to have a radial dependence due to the decrease in pre-organization with increasing donor-acceptor distance from the nanoparticle core. These radially controlled redox modulated MMPCs provides a model for molecular devices such as organic semiconductors, light harvesting devices and molecular magnets.
