Membrane Environment Enables Ultrafast Isomerization of Amphiphilic Azobenzene -INVITED [PDF]
EPJ Web of Conferences, 2020 We report on the isomerization dynamics of an amphiphilic azobenzene that dwells within the plasma membrane. We found that in aggregates formed in water, the isomerization reaction is hindered, while radiative deactivation is favoured.

Conformational photoswitching of a synthetic peptide foldamer bound within a phospholipid bilayer [PDF]
, 2016 The dynamic properties of foldamers, synthetic molecules that mimic folded biomolecules, have mainly been explored in free solution.We report on the design, synthesis, and conformational behavior of photoresponsive foldamers bound in a phospholipid ...

The still unknown azobenzene - Wavelength dependent photoanisotropy in amorphous azobenzene polymers
Optics Express, 2013 We demonstrate a new type of anisotropy in thin films of amorphous azobenzene polymers induced between 570 and 633 nm, where the absorbance in the film is on the order of 0.05. The anisotropy has a pronounced radial contribution. This observation points to an additional mechanism for the alignment of azobenzene molecules.

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. A typical photochromic compound, azobenzene, has been studied extensively in the solution state and has played a crucial role in the photomechanical ...
