Position-dependent effects of internal heavy atoms on highly resolved electronic spectra and luminescence properties of some quinoxalines substituted at the homocyclic ring was written by Lewanowicz, A.;Lipinski, J.;Ruziewicz, Z.;Szymczak, A.;Szynkarczuk, J.. And the article was included in Journal of Luminescence in 1989.Related Products of 5448-43-1 This article mentions the following:
Highly resolved phosphorescence and S1(n,π*) S0 phosphorescence excitation spectra and some photophys. properties of monohaloquinoxalines (I; R = H, R1 = Br, Cl; R = Br, Cl, R1 = H) are compared. Exptl. data are supplemented by theor. study of the electronic structures, performed with the use of a modified INDO CI method. Insensitivity of phosphorescence lifetimes of I to the nature of the solvent is discussed. The substituent position-dependent T1 state energy is recognized as the main factor differentiating the vibronic structure of the phosphorescence spectra and the luminescence properties of I. In the experiment, the researchers used many compounds, for example, 6-Chloroquinoxaline (cas: 5448-43-1Related Products of 5448-43-1).
6-Chloroquinoxaline (cas: 5448-43-1) belongs to quinoxaline derivatives. Quinoxaline is isomeric with other naphthyridines including quinazoline, phthalazine and cinnoline. Quinoxalines are used as dyes, pharmaceuticals, and antibiotics such as echinomycin, levomycin exhibiting antitumoral properties. Quinoxalines establish also the basis of anthelmintics and receptor antagonists.Related Products of 5448-43-1
