摘要

Abstract: Three new azobenzenophane-type crown ethers, cr (0,). cr (Og), and cr (Op), 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 were isomerized thermally or by visible light to the trans isomers, the interconversion being completely reversible. The solvent extraction showed that the trans ...
