Building stimuli-responsive supramolecular materials enables spatiotemporal control over complex systems, and is a promising strategy for a range of applications. Here, mixing adenosine 5’-triphosphate (ATP) with an azobenzene-guanidium compound possessing photodependent nucleotide binding affinity is shown to result in the spontaneous photo-reversible self-assembly of these compounds into micrometer-sized fluorescent aggregates that display dynamic responses to several chemical, physical and biological stimuli.
