Abstract：
Chemistry in a Capsule: Manipulating Photochemical Processes Through Confinement and Weak Interactions
- Ramamurthy
Department of Chemistry, University of Miami, Coral Gables, FL, USA
Chemical reactions occur in all three states of matter (gas, liquid and solid). But the most important chemical reactions in biological systems are distinct in occurring in confined environments in water often times on cell surfaces. Entrapment of molecules and understanding their behavior in relation to their micro- and macro environments is thus important in gaining knowledge on the functioning of the animate and inanimate objects around us and creating new materials and devices. Reactions in the biological systems are highly selective while those in gas phase and in organic solvents tend to yield a mixture of products. A long cherished goal of photochemists has been to achieve selectivity in photoprocesses (chemical and physical) through the use of confining media and weak interactions. Results of our studies on the excited state behavior of organic molecules enclosed within molecular containers in aqueous medium and on inert (silica, clay, -ZrP) and active (TiO2 and gold nanoparticle) surfaces will be presented.
Ramamurthy (Murthy) following early education in India (B. Sc and M. Sc degrees) moved to USA for graduate and postdoctoral education. Following training in the laboratories of Professors R. S. H. Liu (University of Hawaii; Ph. D. degree), P. de Mayo (Uni. Western Ontario; postdoctoral studies) and N. J. Turro (Columbia University; postdoctoral studies), Murthy returned to India in 1978 to take up an Assistant Professor position at Indian Institute of Science, Bangalore where he conducted research in organic photochemistry till 1987. In 1987 Murthy moved to the DuPont Company, Wilmington and continued to research on fundamental problems related to supramolecular chemistry, solid-state chemistry and zeolite chemistry (1987-94). In 1994 he returned to academic setting and continued his teaching and research activities at Tulane University (1994-2004; Bernard-Baus Professor of Chemistry) and University of Miami (2005-). While at DuPont Murthy edited a monograph “Photochemistry in Organized and Constrained Media” in 1991 that led to a series titled “Molecular and Supramolecular Photocehmistry” (14 volumes, 1994-2004). Recently he co-authored a textbook “Modern Molecular Organic Photochemistry” (N. J. Turro,V. Ramamurthy and J. C. Scaiano. Ramamurthy has authored over 350 scientific publications and co-edited 20 monographs and special issues for various journals. In addition to being a researcher and administrator (department chair 2004-1013), he also serves as a Senior Editor for the ACS journal Langmuir.
