Photochemistry in Constrained Spaces: Zeolites and Layered Double Metal Hydroxides. Progress Report, August 1, 1992--September 15, 1993

The authors have continued their research in the field of preparation and reactions of photochemical systems in zeolites and layered lithium aluminates. The study on zeolite focused on faujasitic zeolites. The experimental strategy is to build Ru(bpy){sub 3}{sup 2+} inside the supercage and examine the photoelectron transfer from this entrapped complex to acceptor molecules (viologens) through the ring openings. The effort on layered lithium aluminum double hydroxides (LDH) of composition LiAl{sub 2}(OH){sub 6}{sup +}X{sup {minus}} has been on incorporation of photoactive molecules in these interlayers, with particular emphasis on pyrene and Zn porphyrins
