Optically active azophenolic crown ethers 1 and 2 incorporating two cis-1-phenylcyclohexane-1,2-diol chiral subunits and a p-(2,4-dinitrophenylazo)phenol moiety as a chromophore have been prepared and the enantiomer recognitive coloration in complexation with chiral ethylamine and 2-aminoethanol derivatives has been examined. The observed enantiomer selectivities of crown ethers 1 and 2 have been interpreted on the basis of CPK molecular model examination of the diastereoisomeric complexes.
