We constructed a novel molecular conformational alteration system with an N-aryl-N-phenylacetamide structure, in which the N-aryl groupconsists of a hydroquinone-p-quinone system as a redox-dependent aromatic trigger. The amide conformation depended on the oxidationstate of the aryl group, and the two states (compounds 2 and 3) were reversibly converted to each other by redox reactions. Such compoundswould be applied as useful structural units for external stimulus-responsive control on the shape and function of large molecules orsupramolecules.
