Our research has been focused on designing and synthesizing functional nanostructured materials via the self-organization and polymerization of lyotropic liquid crystal (LLC). One of our new research directions in this field is the incorporation of a fluorescent chemical sensing group into these nanoporous resins to generate new solid-state sensors with molecular-size exclusion capabilities and/or enhanced performance. A novel monomer containing a 4-aminophthalimide-based fluorescent headgroup was designed and synthesized. This monomer will be templated into an inverted hexagonal LLC phase by co-polymerization with LLC structure-directing agent. This poster will present the synthesis of the mesogen, as well as the formation and polymerization of nanostructured resin. The impact of solution pH, transition-metal ion complexation, and solvent environment on fluorescence emission of the resulting sensor will be discussed.
