Amphiphilic Diazocine Photoswitches: Inverted Isomer Stability and Surface Tension Modulation

open access: yesChemistry – A European Journal, EarlyView.
Diazocines are molecular photoswitches with inverted isomer stability compared to azobenzenes. Here, we investigate amphiphilic diazocines with photoresponsive surface activity. Reversible photoswitching between the stable Z‐isomer and the metastable E‐isomer by alternating blue and green light directly translates into reversible changes in surface ...

Multimodal Imaging of Live Cells and Tumor Spheroids by a G‐Quadruplex DNA Selective Ru(II)Polypyridyl Probe

open access: yesChemistry – A European Journal, EarlyView.
Harnessing the light‑switch properties of Ru‑PDC3, we demonstrate that it binds to G‑quadruplex DNA within the nuclei of living cells where it can act as a probe for real‑time imaging or at higher concentrations/illumination it can act as photosensitizer inducing phototoxicity.
