Two-dimensional networks of an azobenzene derivative: bi-pyridine mediation and photo regulation

Two-dimensional photosensitive supramolecular assemblies based on an azobenzene derivative and bi-pyridine are built up and investigated using scanning tunneling microscopy (STM). In order to probe the photo-induced self-assembled behavior of these two molecules, irradiation experiments with differe...

Zusammenfassung:Two-dimensional photosensitive supramolecular assemblies based on an azobenzene derivative and bi-pyridine are built up and investigated using scanning tunneling microscopy (STM). In order to probe the photo-induced self-assembled behavior of these two molecules, irradiation experiments with different wavelengths are designed and performed. Our STM results show that the constructed H-bonded networks can be reversibly regulated under irradiation with UV light and visible light.
