WebAnions, Solution chemistry, Spectroscopy, Materials Abstract Molecular recognition of an aqueous pertechnetate (TcO 4–) anion is fundamentally challenging partly due to the charge-diffuse nature of this anion, which hampers design of new technologies for its separation and detection. WebThe perrhenate anion is tetrahedral, being similar in size and shape to perchlorate and the valence isoelectronic permanganate. The perrhenate anion is stable over a broad pH … bingo number generator free online uk

WebJan 5, 2024 · In the anti-interference study, it was found that phosphate has an influence on the sensing performance of UiO-66-NH 2 towards lysine and arginine implying that UiO-66-NH 2 may be used as a fluorescence probe for phosphate. Therefore, the sensing capability of UiO-66-NH 2 for varied anions was explored in this work. WebSupramolecular recognition of perrhenate is a challenging task due to therelatively large size and low charge density of this anion. In this work, we design and synthesize a family of helix-like synthetic receptors that can bind perrhenate by forming hydrogen bonds with all four oxygen atoms of the anion. WebFeb 3, 2015 · Abstract. A halogen bonding bis-iodotriazolium water-soluble acyclic receptor exhibits enhanced perrhenate anion recognition in water compared to the hydrogen … bingo number generator wheel
