Our research program involves the design, synthesis, and detailed physical investigation of novel molecular and nanoparticle materials which display unique self-organized hierarchical structures and specific optical, electronic, andor magnetic properties. Emphasis is placed on materials with potential applications in light-emitting devices, optical memory devices, molecular level and single particle level switching devices, and chemosensory devices

he term \organic\ appears to have been used for the first time about 1777 and was applied to those materials occurring in or derived from living organisms. Accordingly, such substances as starch, alcohol, and urea were classified as organic. for starch is produced by living plants, alcohol is a product of fermentation caused by
