Mechanochemical Activation of a Bridged‐Exciplex Optical Force Probe

Advanced Science, EarlyView.
A bridged‐exciplex optical force probe is synthesized, switching from solvatochromic charge‐transfer emission in the latent state to intense locally excited emission upon activation. This dual photophysical response with additional changes in quantum yield and fluorescence lifetime enables precise environmental sensing and distinct optical readouts ...

Metal-free atom transfer radical polymerization with ppm catalyst loading under sunlight

Nature Communications, 2021
Organocatalytic atom transfer radical polymerization (O-ATRP) is attractive due to its metal-free nature but catalysts are rarely applied at a low loading. Here the authors introduce a catalyst design logic based on heteroatom-doping of polycyclic arenes,

ROS‐Responsive Nanoparticle Delivery of Dexmedetomidine Protects the Gut Vascular Barrier After Intestinal Ischemia/Reperfusion via the HDAC‐H3K27ac‐TCF4 Axis

Advanced Science, EarlyView.
A low dose of dexmedetomidine, delivered by ROS‐responsive nanoparticles, preferentially accumulates in the ischemic intestine and restores gut vascular barrier integrity after ischemia/reperfusion injury. This nanoparticle‐based strategy prevents bacterial translocation and liver damage without cardiorespiratory side effects, working through HDAC ...

Controlled Atom Transfer Radical Depolymerization

Advanced Science, EarlyView.
Controlled atom transfer radical depolymerization allows for precise, uniform shortening of polymer chains to yield monomers on demand. By tuning catalyst concentration and temperature, this strategy prioritizes deactivation to maintain molecular weight control throughout depolymerization.
