Optically Switchable NIR Photoluminescence of PbS Semiconducting Nanocrystals using Diarylethene Photoswitches

Journal of the American Chemical Society, 2022
Precisely modulated photoluminescence (PL) with external control is highly demanded in material and biological sciences. However, it is challenging to switch the PL on and off in the NIR region with a high modulation contrast.

Ring closing reaction in diarylethene captured by femtosecond electron crystallography [PDF]

, 2013
The photoinduced ring-closing reaction in diarylethene, which serves as a model system for understanding reactive crossings through conical intersections, was directly observed with atomic resolution using femtosecond electron diffraction.

Enhancing tetraphenylethene cyclization as photoswitch

Smart Molecules, 2023
Tetraphenylethene (TPE), a star building block with promising aggregation‐induced emission, has received much interest. Given that its intramolecular Woodward‐Hoffmann cyclic intermediate instantaneously converts back to the original state within several

Light-induced photoisomerization of a diarylethene molecular switch on solidsurfaces [PDF]

, 2017
Diarylethenes are molecular switches, the state of which can efficiently be controlled by illumination with ultraviolet or visible light. To use the change in the molecular properties when switching between the two states for a specific function ...
