Plajer, Alex J.;Percastegui, Edmundo G.;Santella, Marco;Rizzuto, Felix J.;Gan, Quan;Laursen, Bo W.;Nitschke, Jonathan R. research published 《 Fluorometric Recognition of Nucleotides within a Water-Soluble Tetrahedral Capsule》, the research content is summarized as follows. The design of aqueous probes and binders for complex, biol. relevant anions presents a key challenge in supramol. chem. Herein, a tetrahedral assembly with cationic faces and corners is reported that is capable of discriminating between anionic and neutral guests in water. Electrostatic repulsion between subcomponents can be overcome by the addition of an anionic template, or generating a robust covalent framework by incorporating tris(2-aminoethyl)amine (TREN). The resultant TREN-capped, water-soluble, fluorescent cage binds mono- and poly-phosphoric esters, including nucleotides. Its covalent skeleton renders it stable at micromolar concentrations in water, enabling the fluorometric detection of biol. relevant guests in an aqueous environment. Selective supramol. encapsulants, such as 1, could enable new sensing applications, such as recognition of toxins and drugs, under biol. conditions.
