Bifuran-imide: a stable furan building unit for organic electronics†
Oligo- and polyfurans hold many advantages over their thiophene analogues, yet their low environmental stability greatly limits their applications. In this work, we introduce a new building unit, bifuran-imide (BFI), which displays many of the advantageous properties observed for oligofurans, such as strong fluorescence, high solubility, significant quinoid character, and planarity, while also being significantly more stable (both thermally and photochemically) than parent oligofurans. Oligomers and polymers containing BFI show good solid state packing, strong fluorescence, and solubility, which makes them ideal candidates for active materials in organic electronics.
