A logic gate based on a bistable [c2] daisy chain rotaxane decorated with lateral triarylamine units is described, giving rise to an INHIBIT logic function using proton concentration and light as inputs, and producing dual color change and supramolecular self-assembly as outputs. Triarylamine - [c2] daisy chain rotaxane conjugates behave as logic-gates controlled by pH and light modulations to self-assemble in supramolecular fibers.
