| Résumé : |
Poly N-Vinylcarbazole (PVK) is one of the most often used polymer host materials for optoelectronic devices based on molecularly doped systems, due to its good film forming properties, relatively high hole mobility, and large highestoccupied molecular orbital, lowest unoccupied molecular orbital (HOMO-LUMO). Since pur PVK has poor electrontransporting properties. In this work, we present an important synthesis of some of monomers of alkenyl carbazole unsubstituted and substituted in pendent carbazolic group. These monomers are synthesized, in order to put other functions, to polymerize them and to use them in making charge transfer complexes materials. The N-alkenylcarbazole having a short aliphatic chain has been polymerized before, with a great difficulty; either by radical, anionic or by Ziegler-natta systems. The less activity of N-Allyl carbazole is due to the steric effects and to its deficiency in stability by resonance. Aiming to enhance the reactivity of the monomer, we introduced some constituents, attractor of electron; aiming by this to diminish the influence of the carbazolic groupe on the double bonds of the aliphatic chain and hopping that we will obtain polymers that manifest some photoelectric activities. |
