Rewriting Polymer Fate via Chemomechanical Coupling

open access: yesAdvanced Materials, EarlyView.
This work introduces a life‐like “living” polymer platform that can grow, degrow, and reprogram its properties after fabrication. By integrating mass transport, reversible polymerization, and controlled catalysis, the material achieves on‐demand changes in size, shape, and mechanical properties.

Mechanism‐Guided Precision Hydrolysis of Early Transition Metals to Access (Mixed‐Metal) Oxo Clusters

open access: yesAngewandte Chemie, EarlyView.
Precision hydrolysis enables the rational, room‐temperature synthesis of Zr and Hf oxo clusters with improved atom economy, sustainable solvents, and gram‐scale yields. By adding exactly 1.33 equivalents of water, Zr6, Hf6, and elusive bimetallic clusters are accessed, alongside new group 5 oxo clusters, providing a versatile and economical platform ...

2D MOF with Intrinsic Porosity for Colorimetric Volatile Organic Compounds (VOCs) Detection

open access: yesAdvanced Materials, EarlyView.
An uncommon 2D MOF with intrinsic in‐plane porosity that can be mechanically exfoliated undergoes a distinct and reversible colour change upon exposure to various volatile organic compounds. ABSTRACT In this work, we report an uncommon 2D metal–organic framework (MOF) with intrinsic in‐plane porosity that undergoes a distinct and reversible colour ...

NiH‐Catalyzed Enantioconvergent α‐Alkenylation of Carbonyl Compounds via Markovnikov Alkyne Hydronickellation

open access: yesAngewandte Chemie, EarlyView.
A NiH‐catalyzed α‐alkenylation via Markovnikov hydronickellation of alkynes enables convenient access to α‐chrial β‐methylene carbonyl frameworks that are prevalent in biorelevant molecules. High regio‐ and enantioselectivities have been achieved with excellent functional group tolerance and applicability toward complex structures. The β‐methylene unit
