Graft Copolymer‐Stabilized Liquid Metal Nanoparticles for Lithium‐Ion Battery Self‐Healing Anodes

Advanced Functional Materials, EarlyView.
This study presents a self‐healing liquid metal anode for lithium‐ion batteries, where graft copolymer‐stabilized eutectic gallium indium (EGaIn) nanoparticles enhance stability and rate performance. The fluorinated grafted copolymer forms ionic channels, preventing EGaIn aggregation and facilitating lithium‐ion migration.

Self‐Reinforcing Degradation of Solution‐Processed Small‐Molecule OLEDs: Excited‐States and Molecular Interactions as Key Triggers

Advanced Functional Materials, EarlyView.
Self‐reinforcing degradation in solution‐processed small‐molecule organic light‐emitting diodes (OLEDs) arises from charge accumulation and exciton‐polaron interactions, leading to molecular aggregation and efficiency loss. This study uncovers the fundamental mechanisms behind this degradation and introduces strategic material engineering approaches ...

Fluorophobic Effect Enables Selective Detection of PFAS in Water with Electrolyte‐Gated Organic Transistors

Advanced Functional Materials, EarlyView.
PerFluoroAlkyl Substances (PFAS) are responsible of major and persistent environmental pollution worldwide. This work demonstrates an ultra‐sensitive sensor for PFAS based on an organic transistor whose gate is functionalized with a binary self‐assembled monolayer containing a perfluorinated molecule.

The Dark Side of Fluorine.

ACS Medicinal Chemistry Letters, 2019
Despite the perceived stability of the C-F bond, chemical instability and drug-metabolizing enzymes can lead to its cleavage. The resulting release of fluoride and formation of certain metabolites may cause safety issues and warrant the medicinal ...
