Tuning the electrochemical and optical properties of donor-acceptor D-A2-A1-A2-D derivatives with central benzothiadiazole core by changing the A2 strength was written by Pluczyk-Malek, Sandra;Honisz, Damian;Akkuratov, Alexander;Troshin, Pavel;Lapkowski, Mieczyslaw. And the article was included in Electrochimica Acta in 2021.Name: 5,8-Dibromoquinoxaline This article mentions the following:
Two mols. named QXBT and BXBT with donor-acceptor D-A2-A1-A2-D type of structure were synthesized and characterized by electrochem. (Cyclic and Differential Pulse Voltammetry), spectroscopic and spectroelectrochem. (UV-visible-NIR, Fluorescence and ESR) techniques to evaluate the impact of different A2 acceptors on properties of such compounds with benzothiadiazole as A1 central core and alkylthiophene donor moieties. In the case of QXBT, the quinoxaline and in the BXBT mol. the benzoxadiazole serves as a A2 unit. The studies revealed that changing the A2 allows to tune the conjugation of mols. and affects not only reduction but oxidation process as well. In the experiment, the researchers used many compounds, for example, 5,8-Dibromoquinoxaline (cas: 148231-12-3Name: 5,8-Dibromoquinoxaline).
5,8-Dibromoquinoxaline (cas: 148231-12-3) belongs to pyrazine derivatives. Pyrazines are volatile compounds that are used in the cosmetic, food, flavor, and fragrance industries. Pyrazine-based skeletons were incorporated into agents targeting a range of ailments. Many derivatives were synthesized and evaluated as potential cancer treatments.Name: 5,8-Dibromoquinoxaline
