Three new azobenzenophane-type crown ethers, cr(O7), cr(O8), and cr(O9), in which 4,4' positions of azobenzene are linked by a polyoxyethylene chain, were synthesized.The trans isomers were isomerized by UV light to the cis isomers, and the cis isomers we

A new photoresponsive crown ether (2) in which the poly(oxyethylene) chain is linked to 4- and 4' position of azobenzene was synthetized.Trans-(2) completely lacked the affinity to alkali metal cations, while photoisomerized cis-(2) was capable of binding
