Abstract
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.
Highlights
Switchable molecular machines act by essence as logic gates and can reset a device to its initial state by taking advantage of their reversible bistability
Examples in which an optical output is accompanied by the formation of a supramolecular self-assembly built on the molecular logic unit are scarce and mainly consist in the formation of physical gels
We studied the behavior of triarylamine derivatives 4–9 upon visible light stimulation
Summary
We have shown that this nucleation/growth process leads to doped supramolecular polymers which display outstanding electric conduction properties with optical, magnetic, and electronic signatures of metallic materials.9 we have reported that these triarylamine units can be modified with various chemical units such as terpyridine, fullerene, or gallate moieties while retaining their general ability to selfassemble upon light stimulation in chlorinated solvents.10 during the course of our studies, we noticed the impact of the steric hindrance close to the amide function which is of importance to stabilize the self-assembled structures by intermolecular hydrogen bonds.
