poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt-(9-(2-ethylhexyl)-carbazole-3,6-diyl)], widely known as PF8Cz, is a copolymer consisting of dioctyl-fluorene and ethylhexyl-carbazole. PF8Cz can be synthesised from 3,6-dibromo-9-(2-ethylhexyl)-9H-carbazole and 2,2'-(9,9-dioctyl-9H-fluorene-2,7-diyl)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) through a Pd-catalysed Suzuki coupling reaction. Due to the rigidity of fluorene and carbazole, PF8Cz has a lower energetic disorder than TFB. PF8Cz has HOMO onset energy level at −5.4 eV and LUMO energy level of −2.3 eV, showing an optical bandgap of 3.06 eV.

A band-bending characteristics study of PF8Cz has been conducted using on low-work-function samarium (Sm) substrates. The surface work function of the PF8Cz film on Sm are almost constant, suggesting that PF8Cz has a superior electron-blocking property.
