Reversible Actuation via Photoisomerization-Induced Melting of a Semicrystalline Poly(Azobenzene).
ACS Macro Letters, 2020 Photoisomerization of azobenzene in polymer matrices is a powerful method to convert photon energy into mechanical work. While most previous studies have focused on incorporating azobenzene within amorphous or liquid crystalline materials, the limited ...

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.

Influence of the porosity on the photoresponse of a liquid crystal elastomer [PDF]
Royal Society Open Science, 2016 Azobenzene containing liquid crystal elastomers (LCEs) are among of the most prominent photoresponsive polymers due to their fast and reversible response to different light stimuli.

Manipulating azobenzene photoisomerization through strong light–molecule coupling [PDF]
Nature Communications, 2018 The formation of hybrid light–molecule states (polaritons) offers a new strategy to manipulate the photochemistry of molecules. To fully exploit its potential, one needs to build a toolbox of polaritonic phenomenologies that supplement those of standard ...
