Specifications | MSDS | Literature and Reviews | Technical Support
PF8Cz is a copolymer consisting of dioctyl-fluorene and ethylhexyl-carbazole. It can be synthesized 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 palladium-catalyzed Suzuki coupling reaction.
Due to the rigidity of fluorene and carbazole, PF8Cz has a lower energetic disorder than TFB. It also has a 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.
