Poly(9,9-dioctylfluorene-alt-bithiophene), also known as F8T2 (CAS number 210347-56-1), is a semiconducting material that is widely used in organic electronics such as organic photovoltaics, polymer light-emitting diodes (PLED) and organic field-effect transistors (OFETs). Comparing with poly-3-hexylthiophene, F8T2 has even higher mobilities of 0.1 cm2/V·s and relatively higher stability against chemical doping by environmental oxygen or residual impurities such as mobile sulphonic acid in the PEDOT:PSS ink. This enables devices with higher on-off current ratios exceeding 105 and with better operating stability than printed poly-3-hexylthiophene devices[1].
The absorption in the blue region of F8T2 makes it an excellent donor polymer to blend with an acceptor having complementary spectrum or assemble a tandem cell with other low bandgap-conjugated polymers with absorption extended in the red region.
