Photoswitchable Spasers with a Plasmonic Core and Photoswitchable Fluorescent Proteins [PDF]

Scientific Reports, 2019
AbstractPhotoswitchable fluorescent proteins (PFPs) that can change fluorescence color upon excitation have revolutionized many applications of light such as tracking protein movement, super-resolution imaging, identification of circulating cells, and optical data storage. Nevertheless, the relatively weak fluorescence of PFPs limits their applications

Photoswitching Conduction in Framework Materials

Advanced Functional Materials, EarlyView.
This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

Membrane‐Penetrating Molecular Device Based on a Triplex Containing Acyclic L‐Threoninol Nucleic Acid Functionalized with Cholesterol

Angewandte Chemie, EarlyView.
A membrane‐penetrating molecular device composed of triplex containing cholesterol‐modified acyclic L‐threoninol nucleic acid (L‐aTNA) was achieved. This device is applied to a photo‐triggered signal transduction system functioning on giant unilamellar vesicles. Abstract Membrane‐penetrating molecular devices are valuable biological tools.

Unusual Swelling Behavior of Hydrogels Modified with Spiropyran as Appendage or Crosslinker

Advanced Functional Materials, EarlyView.
Not so innocent after all—spiropyran crosslinkers in methylenebisacrylamide‐crosslinked poly(acrylamide‐co‐acrylic acid) hydrogels increase crosslinking density, but also, counterintuitively, increase swelling. Charge complexation, cooperative chemo‐mechanical effects, and aggregation may explain these observations.

Acid‐ and Nucleophile‐Gated Photoisomerization of Phosphaindirubin

Angewandte Chemie, EarlyView.
Triply gated isomerization: In polar solvents, a phosphorus‐containing indirubin photoswitch undergoes visible‐light‐driven Z→E isomerization only when protonated, and reverts thermally via nucleophile‐catalyzed back‐isomerization. This three‐way control by light, acid, and nucleophile enables reversible photoisomerization.
