A biodegradable molecularly imprinted polymer porous silica sensor enables dual optical readout of doxorubicin via fluorescence and effective optical thickness shifts. The combined transduction mechanisms provide enhanced reliability and quantitative accuracy over clinically relevant concentrations, representing a step toward transient implantable ...

This study shows that a local, data‐driven AI model can accurately predict diverse optical and chiroptical properties of [6]helicenes using information from close structural neighbours. Combined with genetic algorithms, it enables inverse design for tailored properties, establishing practical structure–property rules for efficient molecular discovery ...

Operando real‐time current density–voltage absorption spectroscopy visualizes spatial phase evolution in mixed‐halide perovskites from device to module scale. Phase instability preferentially initiates in regions with insufficient carrier extraction, revealing electrical boundary conditions as governing factors.

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 ...

Structurally Enhanced Colloidal Molecules via Carbene‐Mediated Covalent C─H Insertion Crosslinking
This work presents a nonspecific covalent crosslinking strategy to significantly enhance the structural stability of colloidal molecules (CMs) without compromising their inherent structural and physicochemical properties by rationally designing a diazo‐based crosslinker.

Increasing nanocurvature effectively enriches the local electron density of the M–N4 motif, which facilitates electron transfer from the metal center to nitrogen atoms. This electronic behavior intensifies the localization and asymmetric distribution of charge, thereby significantly amplifying the dipole moment and polarizability.

A non‐covalent chirality‐induced strategy via chiral solvents is presented to synthesize helical 2D COF nanofibers with high crystallinity, high chirality, and high spin polarization. The helical structure enhances the concentration of photogenerated charges, suppresses exciton recombination, and extends carrier lifetimes, thereby significantly ...
