Membrane-targeted push-pull azobenzenes for the optical modulation of membrane potential

Light: Science & Applications
We introduce a family of membrane-targeted azobenzenes (MTs) with a push-pull character as a new tool for cell stimulation. These molecules are water soluble and spontaneously partition in the cell membrane.

Light‐Modulated Humidity Sensing in Spiropyran Functionalized MoS2 Transistors

Small, EarlyView.
A hybrid material combining molybdenum disulfide (MoS2) and spiropyran for humidity and light responsiveness is developed. Ultraviolete (UV) irradiation tunes the wettability of MoS2 decorated by spiropyran, enhancing the humidity sensitivity. Water adsorption and photochromic doping significantly alter the optoelectronic properties of MoS2 flakes ...

Sensitized Disequilibration of Water‐Soluble Azopolymers

Angewandte Chemie, Volume 138, Issue 7, 9 February 2026.
Disequilibration by sensitization under confinement (DESC) is a promising strategy for efficient visible‐light‐induced azobenzene E→Z isomerization. In this article, we explored key factors for adapting DESC to azopolymers, eventually achieving efficiencies up to 85% compared to direct excitation and laying the foundation for more complex systems ...
