Azobenzene molecular glasses with tuned glass transition temperatures : from optimal light‐induced motion to self‐erasable gratings
Diggins, Austin; Dawson, Eoin; Kamaliardakani, Mahnaz; Pellerin, Christian; Sabat, Ribal Georges; Lebel, Olivier (Royal Society of Chemistry, 2020-04-01)The rate of photomechanical formation of surface relief gratings (SRG) in thin films of azobenzene materials depends on their glass transition temperature (Tg), with an optimal Tg around 50–60 °C yielding the fastest SRG growth. Herein, the SRG growth ... -
Molecular-level photo-orientation insights into macroscopic photo-induced motion in azobenzene-containing polymer complexes
Kamaliardakani, Mahnaz; Vapaavuori, Jaana; Xiaoxiao, Wang; Sabat, Ribal Georges; Bazuin, C. Geraldine; Pellerin, Christian (American Chemical Society, 2021-07-13)As part of continuing efforts to deepen the understanding of photo-induced mass transport in azo-containing polymers, we compared the diffraction efficiency (DE) during surface-relief grating (SRG) inscription, photo-induced molecular orientation (<P2>), ... -
Photoresponsive supramolecular polymer films : comparison of the hydrogen and ionic bonding strategies
Kamaliardakani, Mahnaz (2019-03-13)Les complexes supramoléculaires dans lesquels un azobenzène photoactif est lié de manière non-covalente à un polymère représentent des alternatives simples, économiques et flexibles par rapport aux matériaux photosensibles traditionnels de type ...
