Diarylamines with switchable intramolecular H-bonding: a new approach to molecular logic gates

New ortho-substituted diarylamines prone to different types of the intramolecular H-bonding (IMHB) were obtained. In-depth NMR, IR and voltammetry study allowed selecting the amine that demonstrates stable reversible switching of the IMHB bond under the external stimuli, which can be used for the logic gate construction.
