Role of water in intrazeolite photochemistry

Article abstract of DOI:10.1016/0040-4039(96)00971-9

The photochemical and photophysical behavior of several ketones included within Na X zeolites is dependent upon the adsorbed water within the zeolite. Results suggest that when the zeolite is dry (water free), the guest ketones reside within supercages and when the internal structure is filled with water the guest molecules are displaced to the external surface.
