Chemical Research Letters, May 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. , SDS of cas: 94839-07-3, 94839-07-3, Name is Benzo[d][1,3]dioxol-5-ylboronic acid, molecular formula is C7H7BO4, belongs to naphthyridine compound. In a document, author is Tateno, Kotaro, introduce the new discover.
Helical structures were constructed by using pi-spacer-bridged dimers of dibenzopyrrolo[1,2-a][1,8]naphthyridine, which has a highly fluorescent L-shaped pi-extended skeleton. Three dimers with biphenylene (dimer 1), phenanthrene (dimer 2), and m-phenylene (dimer 3) spacers, as well as a fixed-helical dimer 4 where two quinolone rings were covalently cross-linked, were designed and prepared. H-1 NMR and ROESY spectra revealed that dimers 1 and 2 adopted helical forms in solution, whereas dimer 3 did not. The helical conformation of 1 was strengthened by addition of either polar or nonpolar solvents to the chloroform solution, which suggested that pi-pi stacking was the main contributor to the stabilization of the helical structure. All of the dimers, including fixed-helical dimer 4, emitted fluorescence with high quantum yields (phi=0.79-0.86).
The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. I hope my blog about 94839-07-3 is helpful to your research. SDS of cas: 94839-07-3.
