Photochemical reactions of dyes and olefins in monolayer films and supported multilayers.

The studies cited in this paper demonstrate that the unique environment provided by L. B. films and supported multilayers can produce a variety of molecular effects on photochemical reactivity that can, in turn, result in films, interfaces or surfaces having macroscopic properties which can be modulated by light. Although these investigations have been focused on molecular reactivity in films and how it can be modified (or persist unchanged), the results suggest several possible technological applications which might result from investigations directed more closely to them.
