We are interested in using layered inorganic nanomaterials such as the zirconium phosphates and layered double hydroxides for applications ranging from artificial photosynthesis, amperometric biosensors, and drug delivery systems to vapochromic materials. Artificial photosynthesis is one of the most promising ways to capture, convert, and use solar energy efficiently to attend the urgent concern about global warming and climate change due to the constant burning of fossil fuels that increases atmospheric CO₂ levels. The ability to achieve fast forward photoinduced electron transfer (ET) and slow down the energy-wasting back ET is a significant challenge in the development of artificial photosynthesis as a sustainable energy source. We intercalate electron donors into laminar-structured nanomaterials; upon light excitation photoinduced ET between the metal complexes within ZrP and suitable electron acceptors in solution starts a charge separation process that mimics the primary process that occurs in photosynthesis. The chemical microenvironment within the layered inorganic framework promotes electronic coupling between the metal complexes in assemblies at maximum loading enhancing photoinduced charge separation. We have more recently started to use these materials to construct amperometric biosensors using Ru, Co, and Fe-based mediators and to produce vapochromic materials using Pt(II) terpyridyl complexes and their derivatives. We are also intercalating cisplatin, insulin, and C₆₀ for drug delivery applications. The results of these investigations will be presented.
