Nature Chemistry, 2020
The potential applications of smart photoswitchable porous materials are currently limited by incomplete switching. Now, efficient bulk switching has been achieved by embedding a photoisomerizable overcrowded alkene in a highly porous aromatic framework, creating a material capable of photomodulated gas uptake.

Orthogonal Photoswitching with Norbornadiene
Chemistry – A European Journal, 2020AbstractOrthogonal photoswitching is a convenient but challenging way of controlling multiple functions in a system by selective photoisomerization of one unit before the other in any arbitrarily chosen sequence. Here, we present this concept for the norbornadiene/quadricyclane (NBD/QC) photo/thermo‐switch in the presence or absence of a coordinated ...

Azobenzene as a photoswitchable mechanophore
Nature Chemistry, 2023Azobenzene has been widely explored as a photoresponsive element in materials science. Although some studies have investigated the force-induced isomerization of azobenzene, the effect of force on the rupture of azobenzene has not been explored. Here we show that the light-induced structural change of azobenzene can also alter its rupture forces ...

Photoswitchable Anapole Metasurfaces
Advanced Optical Materials, 2021Abstract Nonradiating charge‐current configurations have attracted attention in photonics for the efficient localization of the electromagnetic field. Anapole mode is a unique nonradiating state of light induced by the interference of electric and toroidal dipole that possesses rich physics with potential applications in micro ...

Azobenzene photoswitches for biomolecules
Chemical Society Reviews, 2011The photoisomerization of azobenzene has been known for almost 75 years but only recently has this process been widely applied to biological systems. The central challenge of how to productively couple the isomerization process to a large functional change in a biomolecule has been met in a number of instances and it appears that effective photocontrol

Photoswitchable Organic Nanofibers
Advanced Materials, 2007A photoswitchable nanomaterial is presented, electrospun organic nanofibers based on 1',3'-dihydro-1',3',3'-trimethyl-6-nitrospiro [2H-1-benzopyran-2,2'-(2H)-indole]. The switching properties of the nanofibers were investigated by studying the evolution of absorbance with different UV exposure times, photoluminescence lifetime, cyclic ...

Photoswitching, aggregation, and negative photochromism in ionic arylazoisoxazolium photoswitches
Photochemistry and PhotobiologyAbstract The direct introduction of ionic character in azoheteroarenes led to the generation of azopyridinium, azoimidazolium, and azopyrazolium photoswitches, which have previously garnered intriguing application prospects due to their varied Z‐E thermal relaxation ...
