Titanium‐Catalyzed Defluorination of Poly(Vinyl Fluoride) and Poly(Vinylidene Fluoride) Under Friedel–Crafts Conditions

Angewandte Chemie, EarlyView.
Cationic titanium sandwich catalysts display exceptional activity in the hydrodefluorination of Csp3─F bonds, in the presence of silanes and aromatic solvents (turnover numbers up to 3000). As a result, they can be used to defluorinate challenging fluoropolymers, such as poly(vinyl fluoride) (PVF) or poly(vinylidene fluoride) (PVDF).

A Multistage Venturi Amplifier for Rapid Inflation of Soft Robots

Advanced Intelligent Systems, EarlyView.
This work presents the amplifier inflator for soft robotic systems (AIRS), a compact, lightweight, and effective device for rapidly deploying inflatable structures to high pressure. By integrating a check valve with a Venturi‐based air entrainer, AIRS delivers an initial high‐flow output followed by pressurization, supporting fast inflation and ...

A Tert‐Alkyl Terephthalate Derivative as a Universal Degradable Unit for Condensation Polymers

Angewandte Chemie, EarlyView.
A sterically bulky dicarboxylic acid core bearing a tertiary alkyl ester enables photocatalytic C─O bond cleavage via generation of a stabilized tertiary alkyl radical. Incorporated into polyarylate, polyurethane, and polyester, this universal trigger facilitates efficient degradation under identical conditions (up to 99% within 2–4 h). Remarkably, the

HeaTrace: A Parametric Design‐to‐Fabrication Workflow for Thermally Programmable Soft Robots

Advanced Intelligent Systems, EarlyView.
A programmable thermal actuation workflow enables soft robots to be designed and fabricated with embedded heaters that drive multiple responses. By combining performance‐driven heater design with multimaterial fabrication, the system supports thermally triggered shape change, stiffness tuning, and thermochromic visual response, as demonstrated through ...

High‐Tg Polythioesters From Isomerization Ring‐Opening Polymerization of a Renewable Oxanorbornane‐Fused Thionolactone

Angewandte Chemie, EarlyView.
A biobased tricyclic thionolactone undergoes selective isomerization ring‐opening polymerization to yield a high‐molecular‐weight polythioester with an exceptionally high Tg of 171°C, exceeding that of the analogous polyester. The polythioester efficiently depolymerizes through backbiting, while its hydrolysis and methanolysis reveal the critical ...
