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 ...

Photoswitchable Ambiphilicity: Light‐Gated Frustrated Lewis Pair Reactivity and Z‐Type Interaction
Angewandte Chemie, EarlyView.Light‐controlled ambiphilicity is realized in photoswitchable intramolecular phosphorus/boron Lewis pairs. Reversible switching modulates both the thermodynamics and kinetics of frustrated Lewis‐pair reactivity, enabling light‐gated CO2 binding and release.

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 ...
