The authors demonstrate a flexible-linker strategy for mol. organic semiconductors using a common small-mol. donor, 3,6-bis(5-(benzofuran-2-yl)thiophen-2-yl)-2,5-bis(2ethylhexyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione, coded as DPP(TBFu)2. When the flexibly linked material is employed as an additive in thin films, a unique level of control is observed over the morphol. and the thermal stability of pure donor films in transistor devices and in blends with PC61BM for BHJ photovoltaics. The synthesis of the flexibly linked DPP(TBFu)2 derivative [coded FL-DPP(TBFu)2] is shown schematically. The Stille-coupling polycondensation between the brominated diketopyrrolopyrrole core and the stannylated benzofuran dimer followed by standard purification and finally preparatory size exclusion chromatog. afforded the pure polymer with a number average mol. weight, Mn of 10 kDa and a PDI of 1.4 ( n = 11 – 15) in the hundred-milligram scale. In the experiment, the researchers used many compounds, for example, 6-Bromobenzofuran (cas: 128851-73-0Recommanded Product: 128851-73-0).
6-Bromobenzofuran (cas: 128851-73-0) belongs to benzofurans derivatives. Many natural or synthetic compounds containing benzofuran skeletons have been found to possess remarkable activity as agrochemicals and pharmaceuticals. Substituted benzofurans find applications such as fluorescent sensors, oxidants, in drug discovery, and in another field of chemistry and agriculture.Recommanded Product: 128851-73-0
