A carbazole of formula I wherein R1 and R2 are each independently halo, B(OH)2, B(OR7)2, Sn(R8)3, C1-20 hydrocarbyl, or C1-20 hydrocarbyl comprising one or more hetero atoms, R3 is H, halo, C1-20 hydrocarbyl, C1-20 hydrocarbyl comprising one or more heteroatoms, or cyano, R4 and R5 are each independently H, halo, C1-20 hydrocarbyl, C1-20 hydrocarbyl comprising one or more heteroatoms, or cyano, and R7 and R8 are each independently C1-20 hydrocarbyl, provided that R4 and R5 are not both H when R3 is n-octyl, and conjugated oligomers, polymers and co-polymers thereof. Embodiments of the oligomers, polymers and co-polymers can, for example, be formed into films which can be incorporated into electronic devices.

L'invention concerne un carbazole de formule (I) dans laquelle R¿1? et R¿2? désignent chacun indépendamment l'un de l'autre, halo, B(OH)¿2?, B(OR¿7?)¿2?, Sn(R?8¿)¿3?, hydrocarbyle C¿1-20?, ou hydrocarbyle C¿1-20? comprenant un ou plusieurs hétéro-atomes, R¿3? désigne H, halo, hydrocarbyle C¿1-20?, hydrocarbyle C¿1-20? comprenant un ou plusieurs hétéro-atomes, ou cyano, R¿4? et R¿5? désignent chacun indépendamment l'une de l'autre, H, halo, hydrocarbyle C¿1-20?, hydrocarbyle C¿1-20? comprenant un ou plusieurs hétéro-atomes, ou cyano, et R¿7? et R¿8? désignent chacun indépendamment l'un de l'autre, hydrocarbyle C¿1-20?, sous réserve que R¿4? et R¿5? ne désignent pas tous les deux H lorsque R¿3? désigne n-octyle. L'invention concerne également des oligomères, des polymères et des copolymères conjugués dudit carbazole. Des modes de réalisation des oligomères, des polymères et des copolymères peuvent par exemple être des films pouvant être intégrés dans des dispositifs électroniques.
