Light‐Modulated Humidity Sensing in Spiropyran Functionalized MoS2 Transistors

Small, Volume 22, Issue 25, 4 May 2026.
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 ...

Photoacid‐Mediated Controllable Gelation in a Chemical Reaction Cycle

ChemSystemsChem, Volume 8, Issue 3, May 2026.
Visible‐light‐driven photoacid enables programmable hydrogelation in a dissipative CRN: irradiation intensity tunes sol‐gel timing and mechanics via in‐situ formaldehyde formation from hexamethylenetetramine. ABSTRACT We explore the use of a photoacid in a chemical reaction cycle, which allows for the controlled sol‐to‐gel transition of a saccharide ...
