Photomechanical Azobenzene Crystals [PDF]

Crystals, 2019
Photomechanically responsive materials are promising candidates for future smart actuator applications. The photo-responsive behaviors originate from the photoisomerization of photochromic molecules.

Dihydroazulene‐Azobenzene‐Dihydroazulene Triad Photoswitches [PDF]

Chemistry – A European Journal, 2021
AbstractPhotoswitch triads comprising two dihydroazulene (DHA) units in conjugation with a central trans‐azobenzene (AZB) unit were prepared in stepwise protocols starting from meta‐ and para‐disubstituted azobenzenes. The para‐connected triad had significantly altered optical properties and lacked the photoactivity of the separate photochromes.

Reprocessable Photodeformable Azobenzene Polymers [PDF]

Molecules, 2021
Photodeformable azobenzene (azo) polymers are a class of smart polymers that can efficiently convert light energy into mechanical power, holding great promise in various photoactuating applications. They are typically of crosslinked polymer networks with highly oriented azo mesogens embedded inside. Upon exposure to the light of appropriate wavelength,

Halogen bonding stabilizes a cis-azobenzene derivative in the solid state: A crystallographic study [PDF]

, 2017
Crystals of trans- and cis-isomers of a fluorinated azobenzene derivative have been prepared and characterized by single-crystal X-ray diffraction. The presence of F atoms on the aromatic core of the azobenzene increases the lifetime of the metastable ...

Thermal stability improvement of azobenzene for the integration of photochemical and solar thermochemical energy conversion

Case Studies in Thermal Engineering, 2023
Azobenzene is a typical photoisomerization material that is widely used in photochemical energy conversion. However, it's generally operated below 200 °C to avoid thermal decomposition.
