DOCUMENT TYPE: Journal CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Zeolites are often employed as organizational media or supports for entrapped or adsorbed transition-metal catalysts and photocatalysts. In such applications, the individual catalytic species have been assocd. with the framework structure of the zeolite in a purely statistical (randomized) arrangement. A synthetic strategy developed recently has shown how a much higher level of organization can be obtained, so pointing the way to the generation of systems in which two or more active components can be arranged-both spatially and in terms of reactivity-within the zeolite host to enhance the efficiency of a desired catalytic reaction. 7325-63-5 is the cas registry number. This chemical is also mentioned in this article. Here we describe an application of this approach to photochem. storage of light energy. Such an application requires efficient photoinduced charge transfer between donor and acceptor mols. to form long-lived charge-sepd. states: the competing thermal back electron transfer reaction must be minimized. This is achieved in our system by arranging the active components (donor, acceptor and a 'sensitizing' intermediate mol.) such that they occupy adjacent cages within the zeolite framework, and results in unprecedented levels of net charge-sepn. efficiency. .
