Emission color tuning and white-light generation based on photochromic control of energy transfer reactions in polymer micelles [PDF]

open access: yes, 2016
We encapsulate a fluorescent donor molecule and a photochromic acceptor unit (photoswitch) in polymer micelles and show that the color of the emitted fluorescence is continuously changed from blue to yellow upon light-induced isomerization of the ...

Fluorescent Diarylethenes With Polar Groups: Synthesis, Spectra, and Optical Microscopy Applications

open access: yesChemistry – A European Journal, EarlyView.
Blinking green and flashing red: photo‐switchable and photo‐activatable probes emitting green and red light were prepared and applied as bioconjugates in super‐resolution optical microscopy. ABSTRACT The use of photoactivatable fluorescent diarylethenes (fDAEs) in biology‐related light microscopy has been restricted by the lack of probes having freely ...

1,2-Bis[5-(4-cyanophenyl)-2-methyl-3-thienyl]-3,3,4,4,5,5-hexafluorocyclopent-1-ene: a photochromic diarylethene compound

open access: yesActa Crystallographica Section E, 2008
The molecules of the title compound, C29H16F6N2S2, a photochromic dithienylethene with 4-cyanophenyl substituents, adopt an antiparallel arrangement that is reponsible for photoactivity. The molecule lies on a twofold rotation axis.

Many-molecule reaction triggered by a single photon in polaritonic chemistry [PDF]

open access: yes, 2017
The second law of photochemistry states that, in most cases, no more than one molecule is activated for an excited-state reaction for each photon absorbed by a collection of molecules.

Bifunctional Molecular Switches in Fused Diarylethene–Rhodamine Systems

open access: yesChemPhotoChem, EarlyView.
Spectroscopic and time‐dependent density‐functional theory studies show that these novel rhodamine‐based diarylethene (DAE) compounds display intense UV absorption, undergo reversible two‐step protonation involving triazole and rhodamine units, and respond selectively to acid, base, and metal ions.

The effect of the formyl group position upon asymmetric isomeric diarylethenes bearing a naphthalene moiety

open access: yesBeilstein Journal of Organic Chemistry, 2012
Three new isomeric asymmetric diarylethenes with a naphthyl moiety and a formyl group at the para, meta or ortho position of the terminal benzene ring were synthesized.

Light‐Modulated Humidity Sensing in Spiropyran Functionalized MoS2 Transistors

open access: yesSmall, EarlyView.
A hybrid material combining molybdenum disulfide (MoS2) and spiropyran for humidity and light responsiveness is developed. Ultraviolete (UV) irradiation tunes the wettability of MoS2 decorated by spiropyran, enhancing the humidity sensitivity. Water adsorption and photochromic doping significantly alter the optoelectronic properties of MoS2 flakes ...
