In 2022,Delledonne, Andrea; Orlandini, Martina; Mazzeo, Paolo P.; Sissa, Cristina; Bacchi, Alessia; Terenziani, Francesca; Pelagatti, Paolo published an article in Physical Chemistry Chemical Physics. The title of the article was 《Bis-isonicotinoyl linkers containing polyaromatic scaffolds: synthesis, structure and spectroscopic properties》.HPLC of Formula: 523-27-3 The author mentioned the following in the article:
New synthesis of extended linkers containing different polyaromatic chromophores functionalized with isonicotinoyl moieties I (R = 3,7-naphthalene-diyl, biphenyl-4,4′-diyl, fluorene-2,7-diyl, etc.) have been synthesized by Pd-catalyzed cross-coupling reactions involving isonicotinamide and the appropriate aromatic dibromides such as 2,6-dibromonaphthalene, 2,7-dibromofluorene, 9,10-dibromoanthracene, etc. The optimized protocol led to the isolation of the target mols. in good yield and with high purity. Electronic absorption and emission spectra were collected both in solution (DMF) and in the solid state. TDDFT calculations were carried out to investigate the effect of the isonicotinoyl moieties on the spectral features of the central chromophores. After reading the article, we found that the author used 9,10-Dibromoanthracene(cas: 523-27-3HPLC of Formula: 523-27-3)
9,10-Dibromoanthracene(cas: 523-27-3) can be sublimated and oxidized to generate anthraquinone. Soluble in hot benzene and hot toluene, slightly soluble in alcohol, ether and cold benzene, insoluble in water.HPLC of Formula: 523-27-3
