Bridging Performance and Fate: A Framework for Sustainable, Composite‐Based Flexible Electronic Systems

open access: yesAdvanced Electronic Materials, EarlyView.
Composite‐based flexible electronics integrate biodegradable polymers, conductive networks, and multilayer device architectures to balance electrical performance, mechanical durability, and controlled degradation. Interfacial engineering and encapsulation regulate transport stability and operational lifetime, while programmed disassembly enables ...

Controlling Self‐Doping in Conjugated Polyelectrolyte Copolymers to Vary the Threshold Voltage in OECTs

open access: yesAdvanced Electronic Materials, EarlyView.
Two series of self‐doped conjugated polyelectrolytes are synthesized from a non‐self‐dopable building block 3MEEET and a self‐dopable building‐block 3HOT−[TMA+] or 3HOT−[SO3H] enabling precise control over the degree of self‐doping, which in turn directly governs the threshold voltage (VT) in OECTs over a wide range of 700 mV.

Redox‐Modulated σ‐Bond Reactivity in a Radical‐Anion Dimer

open access: yesAngewandte Chemie, EarlyView.
A radialene‐based radical anion σ‐dimer comprising an elongated C‐C bond exhibits orthogonal stimuli responsiveness. Homolytic cleavage of the dimer to the radical state is triggered by mechanical strain and high temperature. Dimer scission is also achieved via oxidation, resulting in formation of neutral radialenes.

Toward a Rational Design of Conjugated Copolymers with Oxygenated Side Chains for Boosting Thermoelectric Properties

open access: yesAdvanced Energy Materials, EarlyView.
The molecular design strategy that integrates both side chain and backbone engineering in diketopyrrolopyrrole‐based conjugated polymers to identify the optimal balance between doping efficiency and microstructural order is demonstrated. Comprehensive spectroscopic, electrochemical, morphological, and structural characterizations reveal that the ...

Rational Backbone Planarization for Doping‐Resilient Polymeric Hole Transport Materials Toward Stable and Scalable Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Incorporating divinylbenzene into PTAA‐based copolymers induces backbone planarization and promotes polaron delocalization, leading to enhanced doping resilience and stabilized electronic structure. The resulting hole‐transport material, PDVB14, maintains robust performance under high dopant concentrations and prolonged device operation, offering a ...

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

open access: yesAngewandte 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).
