On April 30, 1989, Lewanowicz, A.; Lipinski, J.; Ruziewicz, Z.; Szymczak, A.; Szynkarczuk, J. published an article.Category: quinoxaline The title of the article was Position-dependent effects of internal heavy atoms on highly resolved electronic spectra and luminescence properties of some quinoxalines substituted at the homocyclic ring. And the article contained 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. The experimental process involved the reaction of 5-Chloroquinoxaline(cas: 62163-09-1).Category: quinoxaline
