| Abstract: | reaction: see text] Recombinations of prochiral radical pairs from irradiations of 1-naphthyl (R)-2-phenylpropanoate in polyethylene films occur with significant enantioselectivity due to templating effects in the reaction cavities. Photoreactions in PE films in their unstretched or stretched states and of different crystallinity have been employed to distinguish between the characteristics of reaction cavities in amorphous and interfacial regions of the polymer. |
