Novel derivatives of atophan (2-phenylquinoline-4-carboxic acid)

Abstract

Acylation of substituted hydroxybenzaldehydes with hydrochloride of atophane acylchloride in dichloromethane in the presence of triethylamine gave esters, capable of forming (E)-azomethines when condensed with amines (4-aminoazobenzene, 4-aminoantipyrine) in methanol. In addition, an ester of atophane with a natural fragment of curcumin was obtained. Films based on (E)-azomethine with an azobenzene fragment were found to have a high polarizing ability.
