Exactly Restricting the Phenyl Ring Rotation in Metal‐Organic Framework for Ultra‐Sensitive and Specific Ratiometric Fluorescent Sensing of Sarin

Aggregate, EarlyView.
A goal‐oriented MOF design strategy is proposed to realize the ultra‐sensitive and specific detection of sarin/DCP through the rotation restricted emission mechanism. The hydrogen bonding and hydrophobic interaction between the CTTB ligand and DCP efficiently lead to a dramatic change in molecular configuration, significantly enhancing the fluorescence

Lithium extraction from salt‐lake brines using dicationic ionic liquids: ePC‐SAFT modeling and molecular mechanisms

AIChE Journal, EarlyView.
Abstract This work proposes a novel strategy for enhancing Li+ extraction from salt‐lake brines with the high Mg2+/Li+ ratio using dicationic ionic liquid (DIL)‐based extractants. The ternary mixture of the DIL [DOMIM][Tf2N]2, tributyl phosphate (TBP), and dichloromethane (DCM) as a diluent achieved a higher single‐stage Li+ extraction efficiency (86 ...

Interfacial Photoelectrochemistry in Organic Synthesis

Angewandte Chemie International Edition, Accepted Article.
Photoelectrodes have traditionally enjoyed widespread attention as heterogeneous catalysts for the activation of water and CO2 in energy research, while photoelectrochemistry with homogeneous molecular catalysts dominates the activations of more complex molecules in organic synthesis.

Strain‐Release Driven Arsenium Ion Bond Insertion

Angewandte Chemie International Edition, Accepted Article.
Although it marks a cornerstone of pnictenium ion [R2Pn]+ reactivity, the insertion of arsenium ions [R2As]+ into non‐polar bonds remains highly challenging. Herein, a synthetic approach is developed, which circumvents the limitations of insertion reactivity of [R2As]+ (e.g.

Saccharinate‐Based Ionic Liquids and Lithium Battery Electrolytes

Batteries &Supercaps, EarlyView.
Fluorine‐free ionic liquids (ILs) with saccharinate anion coupled to ether‐functionalized pyrrolidinium/imidazolinium cations exhibit promising thermal, transport, and electrochemical properties. The imidazolinium‐based ILs offer higher electrochemical stability, while the pyrrolidinium‐based ILs display superior ion transport.

Laser‐Induced Graphene for Early Disease Detection: A Review

ChemElectroChem, Volume 12, Issue 6, March 15, 2025.
Laser‐induced graphene (LIG) has emerged as a superior alternative to conventionally synthesized graphene due to its flexibility, cost‐effectiveness, scalability, high conductivity, and the ability to customize its properties for various applications. This review highlights LIG′s transformative potential in electrochemical biosensing, focusing on early

Functionalization, Fragmentation, and Expansion of cyclo‐P4R2 Ligands

Chemistry – A European Journal, EarlyView.
Three isolobal transition metal (TM) units are demonstrated to impact the transformation of coordinated P4 ligands in different ways. The observed reactivity primarily depends on the nature of the TM, an effect so far underexplored in phosphorus chemistry. This in‐depth analysis shines light on the underlying mechanistic principles and exploits them to

Studies in organophosphorus chemistry

, 1966
Various methods of alkylation of the >PO₂⁻,>-PS₂⁻ and >POS⁻ ions have been investigated. Ethyl miethylphosphonate reacted with 2-methyloxiran to give ethyl 2-hydroxypropyl methylphosphonate and with p-nitrobenaonitrile oxide to give ethyl 0a-hydroxyimino-4-nitrobenzyl methylphosphonate, a new type of organophosphorus ester, which was shown to hydrolyse

Mg Plating in Nonethereal Electrolyte Solutions: Fact or Misconception?

ChemSusChem, EarlyView.
An overview of Mg electrochemistry in both ethereal and nonethereal electrolyte systems was provided. Comprehensive reviewing on the electrochemical Mg plating/stripping activity reaffirms that only a limited range of solvents support reversible Mg plating/stripping.
