Abstract
A new photosensitive calix[4]arene crown ether with azo unit (1) is st udied. Trans-1 was isomerized by UV light to cis-1 which in turn was i somerized thermally to trans-1. Reversible isomerizations have been ob served and the cis isomer extracts cesium and rubidium better than the trans Isomer. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
