In a article，once mentioned of 41213-32-5

Thirty-five quinoxalines bearing a substituted amiline group on position 2 and various substituents on positions 3, 6, 7 and 8 were prepared in order to evaluate in vitro anticancer activity. Structural elucidation of some isomeric quinoxalinones formed by ring closure of 4-substituted-1,2-diaminobenzenes with dicarbonyl compounds was achieved by comparison with one isomer coming from an unambiguous independent route. Preliminary in vitro screening at NCI showed that many compounds exhibited a moderate to strong growth inhibition activity on various cell lines between 10-5 and 10-4 molar concentrations.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

A series of quinoxaline based metal-free organic sensitizers has been designed and synthesized for dye-sensitized solar cells (DSSCs). The absorption, electrochemical, and photovoltaic properties for all sensitizers have been systematically investigated. It is found that the incorporation of quinoxaline unit instead of thienopyrazine unit results in a negative shift of the lowest unoccupied molecular orbital levels for FNE44, FNE45, FNE46, and FNE47, in comparison to FNE32, which induces a remarkable enhancement of the electron injection driving force from the excited organic sensitizers to the TiO2 semiconductor. Moreover, when the alkyl substituents are removed from the spacer part in FNE44 to the donor part in FNE45 and FNE46, a more conjugated system and a bathochromically shifted maximum absorption band can be realized, which consequently results in an increased light harvesting efficiency and photogenerated current. In addition, the length of the alkyl substituents on the donor part has a certain influence on the DSSC performance. Combining the three contributions, FNE46-based DSSC with liquid electrolyte displays the highest power conversion efficiency (eta) of 8.27%. Most importantly, a eta of 7.14% has been achieved for FNE46 based quasi-solid-state DSSC and remained at 100% of the initial value after continuous light soaking for 1000 h, which indicates that FNE46 is appropriate for promising commercial application. Our findings will facilitate the understanding of the crucial importance of molecular engineering and pave a new path to design novel metal-free organic dyes for highly efficient and stable DSSCs.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 148231-12-3, help many people in the next few years.SDS of cas: 148231-12-3

New Advances in Chemical Research, May 2021. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.49679-45-0, In a article, mentioned the application of 49679-45-0, Name is Ethyl 3-chloroquinoxaline-2-carboxylate, molecular formula is C11H9ClN2O2

Thirty quinoxalines bearing a substituted phenoxy or hydroxybenzoylglutamate group on position 2, a carboethoxy or carboxy group on position 3 and a trifluoromethyl group on position 6 or 7 of the heterocycle were prepared in order to evaluate the in vitro anticancer activity. Screening over 21 compounds selected at the National Cancer Institute (Bethesda, MD) showed that only few derivatives exhibited a moderate growth inhibition activity on various tumor panel cell lines at 10-4 molar concentration. The acid derivatives showed no growth inhibition activity. The results obtained in this series seem to indicate that in general carboxy or carboethoxy groups close to O-link with phenyl or benzoyl glutamates on position 2 are detrimental for anticancer activity.

Novel organosilicon polymers having donor-acceptor type pi-conjugated units in the backbone were prepared by Stille-coupling reactions of bis(tributylstannylthienyl)silanes with diiodoquinoxialine, benzothiadiazole, and benzothiaselenazole. Dehaloganative copolymerization of di(bromothienyl)silanes and dibromoquinoxaline was also studied, which gave the corresponding random copolymer. Applications of these polymers to dye-sensitized solar cells (DSSCs) were examined and it was found that the polymer containing benzoselenadiazole units as the acceptor exhibited the best performance as the sensitizer among the present polymers.
