This proposal describes how molecular and nanomaterials that respond to light and subsequently perform important functions ‘on-command’ will be developed. The projects use light to reversibly change molecular structure and consequently optical, electronic and mechanical properties of molecules or materials. Project examples include (1) controlling chemical and biochemical reactivity, (2) modifying the performance of polymeric materials, (3) detecting the presence of analytes or changes in the environment, (4) controlling optical imaging, and (5) providing novel means to release molecules from the surface of designer nanoparticles. Application areas that will be potentially impacted include catalysis and chemical processing, self-healing polymers, drug-delivery, bio-imaging, and detection and tracking.
