Electrochemical Hofmann Rearrangement for Modular Synthesis of Unsymmetrical Ureas and Late‐Stage Modification of Drugs

open access: yesAdvanced Science, EarlyView.
An electrochemical Hofmann rearrangement of amide involving amine or other amide nucleophiles has been developed. The use of NaI guarantees the feasibility and compatibility of the electrosynthesis protocol, which enables highly chemoselective synthesis of unsymmetrical N‐acylureas from two different amides, as well as the production of unsymmetrical ...

Electronic‐State Polarization Engineering‐Regulated Fluorinated Covalent Organic Framework Nanocables for Fast Lithium‐Ion Storage

open access: yesAdvanced Science, EarlyView.
Electronic‐state polarization engineering is realized by constructing fluorinated COF nanocables on conductive CNTs scaffolds. The polar C─F units generate localized electric fields and strong ion‐dipole interactions, promoting Li+ adsorption and transport.

Remote Magnetomechanical Neuromodulation Uncovers Therapeutic Mechanisms for Alleviating Parkinsonian Symptoms in Freely Moving Mice

open access: yesAdvanced Science, EarlyView.
Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

Bidirectional Photoswitching of a Tailored Azobenzene with Red and Far‐Red Light Involving Triplet Sensitization in an Aqueous System

open access: yesAdvanced Science, EarlyView.
The action spectrum of a tailored azobenzene is shifted toward bio‐optical window through the chemical modification of its singlet and triplet energy levels. Consequently, the bidirectional photo‐switching of azobenzene in physiological conditions is achieved when excited by red and far‐red light, which offers greater tissue penetration.
