Abstrakty

The stable E- and Z-isomers of 10-membered azocrown ether have been isolated and studied by X-ray, 1H NMR and UV-Vis methods. Their structures in a solid state indicate the stretched conformation for trans-isomer and unstressed for cis-isomer. The concerted effect of azo-group _-conjugation with benzene residue and steric strain of molecular conformation results in the observed stability of isomers.
