Thermally Bistable Stiff Stilbene Photoswitches and Polymer Applications
The Chemical Record, EarlyView.Thermally stable photoswitches offer new opportunities for controlling polymer structures and functions under nonequilibrium conditions. This Personal Account highlights stiff stilbene (SS) and sterically hindered stiff stilbene (HSS) photoswitches, which combine large structural changes with exceptional thermal bistability.

Fluorescence switching of photochromic diarylethenes [PDF]
Optical Materials, 2003 Fluorescence switching performance of photochromic diarylethenes has been studied. A bisbenzothienylethene having m-terphenyl substituents underwent reversible photochromic reactions in the amorphous solid state and exhibited fluorescence intensity change and shift of the emission band with the photochromic reaction.

Photo-induced and thermal reactions in thin films of an azobenzene derivative on Bi(111) [PDF]
, 2014 Azobenzene is a prototypical molecular switch which can be interconverted with UV and visible light between a trans and a cis isomer in solution. While the ability to control their conformation with light is lost for many molecular photoswitches in the ...

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations
Advanced Materials Interfaces, Volume 13, Issue 10, 19 May 2026.This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Improving the Fatigue Resistance of Diarylethene Switches
Journal of the American Chemical Society, 2015 When applying photochromic switches as functional units in light-responsive materials or devices, an often disregarded yet crucial property is their resistance to fatigue during photoisomerization. In the large family of diarylethene photoswitches, formation of an annulated isomer as a byproduct of the photochromic reaction turns out to prevent the ...

Phototunable Polarization Volume Gratings Driven by Chiral Hydrazone Switches
Advanced Optical Materials, Volume 14, Issue 19, 22 May 2026.Chiral hydrazone photoswitches incorporated into polarization volume gratings enable light‐driven, reversible modulation of optical properties. UV and blue light irradiation reversibly alter the hydrazone isomer ratio, leading to tunable diffraction efficiency and spectral response across the visible spectrum.
