The class of polyphosphonate covalent organic frameworks is characterised by phosphorus-oxygen-phosphorus bonds, which comprise simple organic phosphonic acid building blocks and -- almost like ...

Among various PFAS, the most potent contributors are linear PFOS, branched PFOS, perfluorononanoic acid, perfluoro-octyl-phosphonic acid, and linear perfluoro-hexane-sulfonic acid.

2-Hydroxybenzylalanine (HBA) and 2-hydroxybenzylaminomethylphosphonic acid (HBAMPA) are chelating ligands that have potential pharmaceutical applications. The molecules are analogues of each other: ...

The researchers also plan to blend sbPA with sulfonic acid ionomers to enhance conductivity by preventing dehydration condensation between phosphonic acid groups. Journal Reference Nakayama, T., et al ...
