    SYNTHESIS AND CHARACTERIZATION OF THE CHARGE TRANSFER COMPLEXES POLYVINYL CARBAZOLE WITH TRINITROFLUORENONE
    (university of eloued جامعة الوادي, 2020-01-01) B., Sakki1,; , Bouras3, O.; A., Haouam1
    Carbazole based polymers are materials of considerable scientific and industrial interest due to their attractive features, such as hole-transporting, high charge-carrier mobility, and electroluminescent properties. Poly (N-vinyl carbazole) (PVK) is easily synthesized, soluble in common organic solvents, poly (N-vinyl carbazole)/2,4,7-trinitro-9-fluorenone (PVK/TNF) charge transfer complex is one of the best-known organic photos conducting materials for application in electrophotography. In the present research, a spectrophotometric method applied for the study of (colored charge transfer complexes) CTC of PVK with TNF reveals the formation of 1:1 (A:D) complex, the formation of CTC with PVK and TNF from the conductivity of the CT Complex. The concentration of the donor is affected when it reacts with the acceptor and that when we increase the concentration of the donor.
