Helical structures were constructed by using 蟺-spacer-bridged dimers of dibenzopyrrolo[1,2-a][1,8]naphthyridine, which has a highly fluorescent L-shaped 蟺-extended skeleton. Three dimers with biphenylene , phenanthrene , and m-phenylene spacers, as well as a fixed-helical dimer where two quinolone rings were covalently crosslinked, were designed and prepared 1H NMR and ROESY spectra revealed that dimers adopted helical forms in solution, whereas m-phenylene dimer did not. The helical conformation of phenanthrene dimer was strengthened by addition of either polar or nonpolar solvents to the chloroform solution, which suggested that 蟺-蟺 stacking was the main contributor to the stabilization of the helical structure. All of the dimers, including fixed-helical dimer , emitted fluorescence with high quantum yields (蠁=0.79-0.86). In the experiment, the researchers used many compounds, for example, 2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1H-naphtho[1,8-de][1,3,2]diazaborinine (cas: 1214264-88-6Related Products of 1214264-88-6).
2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1H-naphtho[1,8-de][1,3,2]diazaborinine (cas: 1214264-88-6) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Converting an alcohol to an alkene requires removal of the hydroxyl group and a hydrogen atom on the neighbouring carbon atom. Dehydrations are most commonly carried out by warming the alcohol in the presence of a strong dehydrating acid, such as concentrated sulfuric acid.Related Products of 1214264-88-6
