(148g) Fundamental Properties of Fluorescent Dyes in Nanoreactors

The properties of organic chromophores inside inorganic nanoreactors are described. Nanoreactors are nanosized containers with semipermeable mineral coatings that regulate the exchange of material between the inside and outside of the reactor, and create a microenvironment that is distinct from the surrounding solvent. The properties of molecules inside nanoreactors is expected to be strongly influenced by the concentration of encapsulated molecules. An organic chromophore is used as probe to better understand how the internal characteristics of nanoreactors are effected by loading concentration. This work is relevant to the design of nanoreactors for chemical processing, as well as the development of photoactive nanostructured materials for sensing applications.
