Reversible C═N Bond Formation Controls Charge-Separation in an Aza-Diarylethene Photoswitch.

Journal of the American Chemical Society
Diarylethenes belong to the most eminent photoswitches and have been studied for many decades. They are found in virtually every field of application and have become highly valuable molecular tools for instilling light-responsiveness into materials ...

Photoinduced Rearrangements of Diarylethenes

Chemistry of Heterocyclic Compounds, 2016
The photocyclization of stilbenes and their heterocyclic analogs has gained major importance in the synthesis of poly(hetero)aromatic compounds. This reaction generally leads to the formation of phenanthrene derivatives or their isosteric heterocyclic analogs. Over the last 15 years, examples of a new type of diarylethene reactions have been published,

Nanocrystallization Process of Diarylethene

Molecular Crystals and Liquid Crystals, 2011
We have clarified nanocrystallization process of diarylethene in the reprecipitation method using a derivative, cis-1,2-cyano-1,2-bis(2,4,5,-trimethyl-3-thienyl)ethene (CMTE) as a typical example of diarylethene. The crystal growth was investigated by the time-dependence measurement of crystal size with dynamic light scattering (DLS ...

Zwitterion Interlocked Diarylethene Molecules Order, Unconnected Diarylethene Molecules Disorder

Small
Abstract A diarylethene‐based zwitterionic molecule (DZM) is newly synthesized for the development of smart films exhibiting reversible color change and switchable ionic conductivity in response to external light stimuli. This dual molecular building block is constructed through zwitterionic interlocking and strong phase separation ...

Photosalient Effect of a Diarylethene with a Perfluorocyclohexene Ring

Chemistry - A European Journal, 2016
AbstractCrystals of a diarylethene with a perfluorocyclohexene ring exhibit a remarkable photosalient effect upon UV light irradiation that is attributed to the structural changes that occur when going from open‐ to closed‐ring isomers in the crystalline state, together with the existence of two conformers with different photoconversions compared with ...

The stepwise photochromic reactivity of diarylethene tuned by selective ions and fabrication of a molecular logic circuit

Dyes and pigments, 2021
The tunable photochromic systems have received wide attention in the photoelectronic fields. Herein, we report a diarylethene derivative attached with 2-hydrazylbenzothiazole via Schiff base, which shows the typical photochromic properties upon ...

Diarylethenes in Astrophysics: From Materials to Devices

Molecular Crystals and Liquid Crystals, 2005
ABSTRACT The photochromic properties of transparent/opaque transition and the change of the refractive index (Δn) have been exploited to develop devices for astronomical spectrographs, both as focal plane masks and as dispersive elements (volume phase holographic gratings, VPHGs), respectively.

Photochromism of a Diarylethene Having an Azulene Ring

The Journal of Organic Chemistry, 2012
Diarylethene derivatives incorporating an azulene ring at the ethene moiety were synthesized. One derivative having thiazole rings showed the expected coloration reaction by excitation at 313 nm (to a higher singlet state) but not when excited at 635 nm (S(0) to S(1) excitation).
