Bistable Switching of π‐Conjugation in a Dithienylethene‐Bridged Luminescent Trityl Diradicaloid

Angewandte Chemie International Edition, EarlyView.
Photoswitches that affect π‐conjugation offer a powerful strategy for external manipulation of luminescent diradicals. Dithienylethene‐linked persistent trityl diradicaloids, DTE‐TTM2 and F6‐DTE‐TTM2, exhibit bistable switching of their optical, electrochemical and magnetic properties.

Comparative Performance of Poly(Vinyl Alcohol)/Chitosan Hydrogels Reinforced With Kraft Lignin and Kraft Lignin Nanoparticles

Journal of Applied Polymer Science, EarlyView.
The use of kraft lignin and kraft lignin nanoparticles in poly(vinyl alcohol)/chitosan hydrogels was comprehensively compared. The results showed that a higher loading of lignin nanoparticles than bulk kraft lignin could be incorporated while maintaining favorable hydrogel properties, leading to improved overall performance. ABSTRACT The development of
