Novel acceptor-donor-acceptor (A-D-A) type oligothiophenes incorporating benzothiadiazole (BTDA) and thiadiazolopyridine (TDAPy) as terminal acceptor groups have been developed for small mol. organic solar cells. In vacuum-processed planar heterojunction solar cells the TDAPy-based oligomer showed a power conversion efficiency of 3.15% and a high fill factor of 0.67. In the experiment, the researchers used many compounds, for example, 2-Bromopyridine-3,4-diamine (cas: 189230-41-9Recommanded Product: 2-Bromopyridine-3,4-diamine).
2-Bromopyridine-3,4-diamine (cas: 189230-41-9) belongs to pyridine derivatives. In contrast to benzene, Pyridine’s electron density is not evenly distributed over the ring, reflecting the negative inductive effect of the nitrogen atom. Halopyridines are particularly attractive synthetic building blocks in a variety of cross-coupling methods, including the Suzuki-Miyaura cross-coupling reaction.Recommanded Product: 2-Bromopyridine-3,4-diamine
