Chemically Modular, Nonfluorinated Polymer Adsorbents for Capturing Per‐ and Polyfluoroalkyl Substances (PFAS)

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nonfluorinated polymer networks for PFAS adsorption are synthesized using active ester click chemistry. Incorporating Lewis base ligands along with hydrophilic and hydrophobic co‐monomers leads to high PFOA binding efficiency. Ligand basicity and pH are found to play an important role in PFOA sorption.

Lignocellulosic Triboelectric Materials for Energy Harvesting and Emerging Applications: A Review on Lignin‐Molecular Engineering toward Improved Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Contrasting sustainable biomass with depleting petroleum resources, this review charts the evolutionary timeline of lignin‐based TENGs. We systematically evaluate their fundamental mechanisms, enhancement strategies, and applications in green self‐powered electronics.

Smart Functional Hydrogels: Emerging Platforms for Thermal and Electrochemical Energy Harvesting and Conversion Systems

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydrogel exhibits versatile functions, including efficient thermogalvanic conversion under a temperature difference, and acting as a cooling layer/forming a thermally conductive nanoactive composite for thermovoltaic conversion. Additionally, its self‐healing and self‐powered flexibility play a key role in energy storage systems. The growing demand

Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.

Cobalt‐Catalyzed C(sp3)H Carbonylation Enabled by Mo(CO)6

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Cobalt‐catalyzed carbonylative C(sp3)H cyclization of aliphatic amides using Mo(CO)6 as a solid CO surrogate enables efficient access to substituted succinimides under operationally simple conditions. The carbonylation of unactivated C(sp3)H bonds represents an attractive strategy for the synthesis of valuable carbonyl‐containing compounds.

Expanding the Scope of 1,2‐Diazepines Through Alternative Activation Strategies

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Often overlooked due to tedious synthetic routes, 1,2‐diazepines can be found in handful of biorelevant molecules. Previous reports from our group lifted the principal synthetic lock: a rapid and user‐friendly protocol to reach monocyclic 1,2‐diazepines from readily available pyridines and electrophilic activating groups. Herein, we extend the scope of

Chemoselective Aldehyde and Imine Reduction by a Macrocyclic Triazole–Borane Complex Triggered by a Non‐innocent Proton–Hydride Interaction

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
This work describes the study on a new recyclable reagent, based on a macrocyclic triazole–borane complex. It showed high chemoselectivity for aldehyde reduction and reductive amination over ketones. This selectivity is driven by a noncovalent hydride–proton interaction that stabilizes the transition state for aldehydes but is sterically inhibited in ...
