Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Optically active</bold> azobenzenedicarboxylic acid derivatives were synthesized from various amino acids. They reversibly isomerize between <italic>trans</italic> and <italic>cis</italic> forms upon irradiation with UV and visible light. The <italic>trans</italic> isomers are circular dichroism (CD) silent, whereas the <italic>cis</italic> isomers are CD active due to the formation of chiral supramolecular assemblies based on the bent structures of the <italic>cis</italic>‐azobenzene moieties and hydrogen bonding between the carboxy groups.
