The present invention relates to 2-~functionalized and 2,7-difunctionalized carbazoles and 2,7 -carbazolenevinylene oligomers and polymers. More specifically, the present invention relates to a compound of Formula (I): wherein R1 is selected from the group consisting of H, alkyl, and aryl; and wherein R2 and R3 are independently selected from the group consisting of H, alkyl, formyl, hydroxymethyl, trityloxymethyl, acetonitrile, chloromethyl, methylphosphonate, methyltriphenylphosphonium and vinyl. The oligomers and polymers are used in field-effect transistors, light-emitting devices such as light-emitting diodes, and solar cells.

L'invention concerne des carbazoles 2-fonctionnalisés et 2,7-difonctionnalisés et des oligomères et polymères de 2,7 -carbazolènevinylène. Plus spécifiquement, elle concerne un composé représenté par la formule (I), dans laquelle R?1¿ est sélectionné dans le groupe constitué par H, alkyle et aryle ; et R?2¿ et R?3¿ sont sélectionnés indépendamment dans le groupe constitué par H, alkyle, formyle, hydroxyméthyle, trityloxyméthyle, cyanométhyle, chlorométhyle, méthylphosphonate, méthyltriphénylphosphonium et vinyle. Ces oligomères et polymères s'utilisent dans des transistors à effet de champ et des dispositifs électroluminescents tels que des diodes électroluminescentes et des piles solaires.
