A Photochemical Single-Molecule Affinity Switch
A photochemical macrocycle, that incorporates a supramolecular resorc[4]arene receptor cavity and two photodimerizable anthracene moieties, has been investigated by single molecule force spectroscopy under external optical control which proved the repetitive and selective activation and deactivation at the level of individual molecular complexes. This synthetic photochemical single-molecule reaction acts as an intermolecular switch and can be affinity-tuned under external control, which allows new concepts for directed molecular assembly and motional functionalities at the nanoscale in the future.
