Carrier‐Free Stimulus‐Responsive Theranostic Nanoprodrug Enabling GSH‐Consumption‐Promoted Chemo‐Photodynamic Cancer Therapy

Advanced Science, EarlyView.
Leveraging the critical role of glutathione (GSH) in mediating drug resistance and scavenging reactive oxygen species (ROS) in cancer cells, a carrier‐free GSH‐consuming theranostic nanoprodrug, consisting of a BODIPY photosensitizer and the chemotherapeutic drug paclitaxel linked through a GSH‐consuming drug linker, is developed to deeply explore the ...

P‐Directed and Lewis Acid‐Assisted Pd‐Catalyzed Si─Me Bond Activation Enabling Alkyl Exchange at Silicon

Angewandte Chemie, EarlyView.
A new type of Si─Me bond activation enabling catalytic alkyl exchange at Si was developed. It involves a P‐directing group and Pd─Lewis acid cooperation. It enables the conversion of Me3SiCl into silanols with three different organic substituents. ABSTRACT A novel mode of Si─Me bond activation has been unveiled through the cooperative action of a P ...

Enhancement of Dissymmetry Factors Through Axial Elongation of Hetero[n]helicenes

Angewandte Chemie, EarlyView.
A benzofuran scaffolding strategy enables the synthesis of hetero[9]‐, [12]‐, and [15]helicenes. Structural and chiroptical analyses demonstrate that systematic axial elongation increases helical distortion and significantly amplifies luminescence dissymmetry.

Strongly Anisotropic and Rapid Excitons Transport in Organic Crystal

Advanced Science, EarlyView.
The increased exciton diffusion length is beneficial to simplify device design and enhance photoelectric conversion efficiency. But the isotropic exciton diffusion may lead to reduced transport efficiency directed to the charge separation site. Here we have successfully achieved strongly anisotropic and rapid excitons transport in thienopyrrole ...

Electrocatalytic Polarity Inversion of Azlactones: Access to α‐Quaternary Amino Acids with Electron‐Rich SOMOphiles

Angewandte Chemie, EarlyView.
Electrocatalytic polarity inversion of azlactones unlocks their coupling with electron‐rich reaction partners. Triarylamine‐mediated oxidation of the azlactone enolate generates an electrophilic radical intermediate that undergoes selective C4 functionalization with diverse SOMOphiles.
