7-Azaindole has been used in designing new mol. structure 1 on enediyne spacer for its application in anion sensing. New structure 1 has been established as efficient fluorescent sensor of H2PO4– and F– ions in CH3CN containing 1% DMSO. While in presence of H2PO4– the emission at 418 nm is decreased to the significant extent in nonratiometric fashion, a ratiometric response in presence of F– is noted with a sharp isoemissive point and two anions are effectively distinguished over a series of other anions tested. A similar study on model compound 2 with indole motifs is done to prove the pivotal role of extra ring nitrogen in azaindole of 1 in the binding process. In the experiment, the researchers used many compounds, for example, 2-Iodo-1H-pyrrolo[2,3-b]pyridine (cas: 1227270-32-7Product Details of 1227270-32-7).
2-Iodo-1H-pyrrolo[2,3-b]pyridine (cas: 1227270-32-7) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Iodo alkanes participate in a variety of organic synthesis reactions, which include the Simmons–Smith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Product Details of 1227270-32-7
