Phototransformations of 6-X-5-Nitroquinoxalines was written by Rtishchev, N. I.;Selitrennikov, A. V.. And the article was included in Russian Journal of General Chemistry (Translation of Zhurnal Obshchei Khimii) in 2004.SDS of cas: 5448-43-1 This article mentions the following:
Photophys. properties and photochem. activity of 6-X-5-nitroquinoxalines with electron-donor substituents (X = H, CH3, Cl, OC2H5, NH2) ortho to the nitro group were studied. The quantum yield of the formation of 5-hydroxyquinoxaline from the corresponding nitro derivative depends on the nature of the substituent and irradiation conditions. Phototransformations can go through nitro-nitrite rearrangement with the participation of two alternative T(nπ*) levels, depending on the size and electronic effects of the substituent. The latter factor is largely determined by the population on excitation of different charge-transfer states involving the nitro group. In the experiment, the researchers used many compounds, for example, 6-Chloroquinoxaline (cas: 5448-43-1SDS of cas: 5448-43-1).
6-Chloroquinoxaline (cas: 5448-43-1) belongs to quinoxaline derivatives. Quinoxalines are important class of heterocyclic compounds, associated with wider pharmacological applications. They are well-known for application in organic light emitting devices, polymers and pharmaceutical agents. The quinoxaline-containing polymers are applicable in optical devices due to their thermal stability and low band gap.SDS of cas: 5448-43-1
