Journal ArticleDOI
o-Fluoroazobenzenes as Readily Synthesized Photoswitches Offering Nearly Quantitative Two-Way Isomerization with Visible Light
TL;DR: These new azobenzene derivatives can be switched in both ways with high photoconversions, and their Z-isomers display a remarkably long thermal half-life.
Journal ArticleDOI
Visible-Light-Activated Molecular Switches.
David Bléger,Stefan Hecht +1 more
TL;DR: This review provides a summary of the different conceptual strategies for addressing molecular switches in the visible and near-infrared regions of the optical spectrum and tremendously extend the scope of photoswitchable systems for future applications and technologies.
Journal ArticleDOI
A chaotic self-oscillating sunlight-driven polymer actuator
Kamlesh Kumar,Christopher Knie,David Bléger,Mark A. Peletier,Heiner Friedrich,Stefan Hecht,Dirk J. Broer,Michael G. Debije,Albertus P. H. J. Schenning +8 more
TL;DR: A liquid crystalline polymer film doped with a visible light responsive fluorinated azobenzene capable of continuous chaotic oscillatory motion when exposed to ambient sunlight in air is described.
Journal ArticleDOI
ortho-Fluoroazobenzenes: visible light switches with very long-lived Z isomers
Christopher Knie,Manuel Utecht,Fangli Zhao,Hannes Kulla,Sergey A. Kovalenko,Albert M. Brouwer,Peter Saalfrank,Stefan Hecht,David Bléger +8 more
TL;DR: A comprehensive study of the effect of substitution on the key photochemical properties of ortho-fluoroazobenzenes is reported, and the visible light photoconversions, quantum yields of isomerization, and thermal stabilities have been measured and rationalized by DFT calculations.
Journal ArticleDOI
Surface Noncovalent Bonding for Rational Design of Hierarchical Molecular Self‐Assemblies
David Bléger,David Kreher,Fabrice Mathevet,André Jean Attias,Guillaume Schull,Axel Huard,Ludovic Douillard,Céline Fiorini-Debuischert,Fabrice Charra +8 more
TL;DR: Clip chemistry: When a fully deterministic strategy that parallels polymer chemistry is used, mono‐, bi‐, and trifunctional clip‐bearing building blocks form noncovalent surface‐self‐assembled dimers, polymers, and 2D networks, respectively.
