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

open access: yesAngewandte 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 ...

Photoswitchable Ambiphilicity: Light‐Gated Frustrated Lewis Pair Reactivity and Z‐Type Interaction

open access: yesAngewandte Chemie, EarlyView.
Light‐controlled ambiphilicity is realized in photoswitchable intramolecular phosphorus/boron Lewis pairs. Reversible switching modulates both the thermodynamics and kinetics of frustrated Lewis‐pair reactivity, enabling light‐gated CO2 binding and release.

TROP2‐Targeting Chimeras (TRTACs) for Tumor Cell‐Selective Membrane Protein Degradation and Enhanced Drug Delivery

open access: yesAdvanced Science, EarlyView.
TROP2 is identified as a novel tumor‐selective lysosomal‐targeting receptor with established clinical relevance. TROP2‐targeting chimeras (TRTACs) are developed by genetically fusing a TROP2‐binding nanobody to nanobodies against specific target proteins.

Architected Spatially Deterministic Multiscale Phase Segregation in Block Copolymer Composites for Augmented Radiative Cooling

open access: yesAdvanced Science, EarlyView.
Multiscale phase segregation in block copolymers enables spatially deterministic structuring from molecular to macroscopic scales, decoupling solar scattering and infrared emission for augmented radiative cooling. ABSTRACT Passive radiative cooling, which reflects solar irradiation while emitting heat through the atmospheric window, provides a ...

Engineering Atomically Precise Cu4I4 Nanoclusters With Integrated Adsorption and Hydrogenation Functions for Efficient Photocatalytic Nitrate‐to‐Ammonia Conversion

open access: yesAngewandte Chemie, EarlyView.
Efficient photocatalytic nitrate‐to‐ammonia conversion is achieved over an atomically precise Cu4I4 motif through dual‐site cooperation. Lewis‐acidic Cu centers promote nitrate adsorption and activation, while adjacent I sites facilitate active hydrogen generation for stepwise hydrogenation.
