Chemiluminescence intensities of substituted lophines was written by Philbrook, George E.;Maxwell, Michael A.. And the article was included in Tetrahedron Letters in 1964.Reference of 5496-35-5 This article mentions the following:
The intensities of the chemiluminescence and the ir and uv absorption spectra were investigated for lophine, 4-dimethylamino-, 4-acetamino, 4-methoxy, 3,4-dimethoxy, 3,4-diethoxy, 4-methyl, 4-isopropyl-, 4-chloro-, 4-fluoro-, 4-bromo-, 3-nitro, 4-nitro-, 4-phenoxy-, and 4-carboxylophine (substituents in the 2 position on the ring) in 70% Me2SO in 30% N NaOH. The curves, log I/I0 = f(σ) (Hammett) were plotted; I depended linearly on the lophine concentration and could be increased by H2O2. Spontaneous evaporation and spontaneous absorption were not found. All the chemiluminescence processes investigated were explained by the fact that, at times, the same mol. fragment was formed. In the experiment, the researchers used many compounds, for example, 4-(4,5-Diphenyl-1H-imidazol-2-yl)benzoic acid (cas: 5496-35-5Reference of 5496-35-5).
4-(4,5-Diphenyl-1H-imidazol-2-yl)benzoic acid (cas: 5496-35-5) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Reference of 5496-35-5
