Switchable stimulated Raman scattering microscopy with photochromic vibrational probes
Nature Communications, 2021 Probes with reversible fluorescence are useful in super-resolution microscopy, but lack sufficient chemical specificity. Here, the authors engineer alkyne tagged diarylethene to realize photo-switchable stimulated Raman scattering probes with high ...

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 ...

Quantitative Evaluation of Photoinduced Bending Speed of Diarylethene Crystals
Crystals, 2015 We investigated photoinduced crystal bending behavior of various photochromic diarylethenes. In all the diarylethene derivatives we used in this work, the relationship between the initial photoinduced bending speed and the crystal thickness was well ...

STM observation of a single diarylethene flickering [PDF]
Ultramicroscopy, 2007 We report the STM observation of single diarylethene derivatives (DD) embedded into alkylthiol self-assembled monolayers (SAM) on Au(111). Telegraph noise in the data shows that the molecular conductance oscillates between two states. Comparing our results to the ones obtained by other teams observing conductance flickering with systems in the same ...
