Three functionally separated donor-π-acceptor (D-π-A) sensitizers CP-I-III with a cyano group as the electron-accepting group and a pyridine as the anchoring group have been developed for dye-sensitized solar cells (DSSCs). Significantly, the Jsc of CP-II, which contains a benzo[1,2,5]thiadiazole moiety, is much higher than those of CP-I and CP-III, which contain quinoxaline and [1,2,5]thiadiazolo[3,4-c]pyridine groups, resp. This is not only a result of the good photon absorption, but also effective intramol. charge transfer. The conversion efficiency (η) for CP-II-based DSSCs is 4.02 %, which is far better than that of CP-I and CP-III. Also, the η value for CP-II is much higher than that for the reference dye P-II with pyridine as anchoring group. In the experiment, the researchers used many compounds, for example, 5,8-Dibromoquinoxaline (cas: 148231-12-3Application In Synthesis of 5,8-Dibromoquinoxaline).
5,8-Dibromoquinoxaline (cas: 148231-12-3) belongs to pyrazine derivatives. Pyrazine derivatives have antitumor, antibiotic, anticonvulsant, antituberculous and diuretic effects as well as kinase, enzymatic and potent tubulin and FtsZ polymerization inhibitory activities. Pyrazines undergo nearly all of the same reactions as pyrimidines, from nucleophilic substitution (SNAr) to palladium-catalyzed cross coupling reactions.Application In Synthesis of 5,8-Dibromoquinoxaline
