Azo-Dyes-Grafted Oligosaccharides—From Synthesis to Applications

open access: yesMolecules, 2021
Azobenzenes are photochromic molecules that possess a large range of applications. Their syntheses are usually simple and fast, and their purifications can be easy to perform.

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

open access: yesAdvanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

Rhodium-Catalyzed Reaction of Azobenzenes and Nitrosoarenes toward Phenazines.

open access: yesOrganic Letters, 2019
A rhodium-catalyzed annulative reaction between azobenzenes and nitrosoarenes has been developed, leading to a series of phenazines in moderate to good yields.

Optical gating with organic building blocks : A quantitative model for the fluorescence modulation of photochromic perylene bisimide dithienylcyclopentene triads [PDF]

open access: yes, 2014
We investigated the capability of molecular triads, consisting of two strong fluorophores that were covalently linked to a photochromic molecule, for optical gating.

Phototunable Polarization Volume Gratings Driven by Chiral Hydrazone Switches

open access: yesAdvanced Optical Materials, EarlyView.
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.

Modulating the Conductivity of Light-Responsive Ionic Liquid Crystals

open access: yesMolecules
In this work, we describe the phase behaviour and the dielectric and conductivity response of new light-responsive ionic liquid crystals, ILCs, which can be applied as controllable electrolytes.

Aqueous azobenzene switching [PDF]

open access: yesScience, 2017
Photoswitches Photoswitching molecules can enable targeted delivery of drugs in the body, but the body is best penetrated by near-infrared radiation (wavelengths between 700 and 900 nanometers). Most photoswitching processes in molecules require shorter wavelengths, and high light intensities are needed to trigger two-photon processes.
