Abstract

Photoactive species have been immobilized in the interlayer space and on the external surface of smectites to construct photofunctional hybrids. The spatial distribution (separation/distance) of photoactive species has been controlled by using smectites with different layer-charge density and by the co-adsorption of photoinactive species such as organoammonium ions and water-soluble polymers. As a result of controlled spatial distribution of photoactive species, the efficiency of photo-induced events (photoluminescence and photo-induced electron/energy transfer) has been altered.
