On September 5, 2018, Kirilova, E. M.; Puckins, A. I.; Romanovska, E.; Fleisher, M.; Belyakov, S. V. published an article.Product Details of 685-91-6 The title of the article was Novel amidine derivatives of benzanthrone: Effect of bromine atom on the spectral parameters. And the article contained the following:
Several new substituted amidine derivatives of benzanthrone were synthesized by condensation reaction from 2-bromo-3-aminobenzo[de]anthracen-7-one and appropriate aromatic or aliphatic amides. The novel benzanthrone derivatives were characterized by TLC anal., NMR, IR, MS, UV/Vis, and fluorescence spectroscopy. The obtained derivatives have yellow or orange fluorescence in organic solvents. The solvent effect on photophys. behaviors of these dyes was investigated, and the results showed that the introduction of a bromine atom causes a blue-shift of the absorption and emission bands and decrease in the fluorescent quantum yield in comparison with unbromated analogs. The difference in the excited state and the ground state dipole moments was estimated by using the variation of Stokes shift and by semiempirical mol. calculations The crystal structure and packing of four novel dyes has been revealed by the X-ray single crystal structure anal. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).Product Details of 685-91-6
