The role of alkyl substituents in deazaadenine-based diarylethene photoswitches
Beilstein Journal of Organic Chemistry, 2016 Diarylethenes are an important class of reversible photoswitches and often claimed to require two alkyl substituents at the carbon atoms between which the bond is formed or broken in the electrocyclic rearrangement.

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

Light‐Modulated Humidity Sensing in Spiropyran Functionalized MoS2 Transistors
Small, Volume 22, Issue 25, 4 May 2026.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 ...

Interfacial Enrichment and Demetallation of a Zinc Porphyrin in the Ionic Liquid [C4C1Im][PF6]
ChemPhysChem, Volume 27, Issue 8, 28 April 2026.Upon dissolution of zinc porphyrins with long dodecyl chains in the ionic liquid [C4C1Im][PF6], partial [PF6]‐ hydrolysis occurs along spontaneous porphyrin demetallation. Driven by their buoy‐like chains, the free‐base porphyrins extremely enrich at the outermost surface as proven by angle‐resolved X‐ray photoelectron spectroscopy, an interesting ...

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