Multicatalytic Access to Renewable Poly(Silyl Ether)s with Tunable Properties

Angewandte Chemie, EarlyView.
This work presents a one‐pot, multicatalytic approach that combines magnesium‐catalyzed esterification and borane‐mediated hydrosilylation for the synthesis of partially bio‐based poly(silyl ethers). This method allows for the tuning of thermal and mechanical properties, including exceptional extensibility (>3800%), and enables efficient chemical ...

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

Advanced Science, EarlyView.
ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...

Mechanically Triggered Chemical Recyclable Polyethylene‐Like Materials

Angewandte Chemie, EarlyView.
Polyethylene‐like copolymers with benchmark properties are prepared by embedding latent cyclobutene mechanophores to overcome PE's end‐of‐life limits. The mechanophores are inert in service but are selectively opened by solvent‐free ball milling to yield well‐defined telechelic oligomers.

Expanding the Chemical Space of Cyclic Polyphthalaldehyde via Post‐Functionalization

Advanced Science, EarlyView.
In this work, we developed a post‐functionalization approach to achieve water‐soluble cyclic polyphthalaldehyde (cPPA) polymers via click chemistry. ABSTRACT Cyclic polyphthalaldehydes (cPPAs) are hydrophobic cyclic polymers with stimuli‐responsive depolymerization property. The introduction of hydrophilic functionalities to cPPAs is challenging due to
