Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 94839-07-3, Name is Benzo[d][1,3]dioxol-5-ylboronic acid, molecular formula is C7H7BO4, belongs to naphthyridines compound. In a document, author is Tateno, Kotaro, introduce the new discover, Quality Control of Benzo[d][1,3]dioxol-5-ylboronic acid.
Fluorescent Short-Stranded Helical Foldamers Based on L-shaped Dibenzopyrrolo[1,2-a][1,8]naphthyridine
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).
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 94839-07-3. Quality Control of Benzo[d][1,3]dioxol-5-ylboronic acid.
