Noncovalent Bonding, Anion Recognition, and Fluoride Sensing
This community investigates the physical forces that hold molecules together—specifically hydrogen, halogen, and chalcogen bonds—and designs molecular systems that use these forces to selectively detect and bind specific ions, particularly fluoride.
The research focuses heavily on the structural and energetic properties of noncovalent interactions, with a strong emphasis on halogen bonding and hydrogen bonding networks. A significant portion of the work involves the synthesis of supramolecular complexes and Schiff base derivatives designed for the highly selective detection of fluoride ions, often utilizing fluorescent probes. The community also explores the role of these interactions in crystal structures, proton transfer mechanisms, and the definition of newer bonding types such as chalcogen and pnictogen bonds. Computational methods, including quantum chemical analysis, are frequently employed to predict the strength and nature of these interactions.
The largest share of the community's output is found in hydrogen research, accounting for 1.1% of all hydrogen-related papers tracked, followed by fluorine at 1.6% of fluorine research and iodine at 0.8% of iodine research. Hydrogen also contributes the highest absolute number of papers to this group, with 6,688 entries.
This research community comprises 20,860 papers, with the most frequent venues being the Journal of the American Chemical Society, The Journal of Chemical Physics, and Journal of Molecular Structure.
Recent work continues to explore the application of these bonding principles in chiral systems, catalysis, and the development of new fluorescent probes for selective fluoride detection, alongside theoretical studies on the fundamental nature of these noncovalent forces.
