“…The simple process of polymerization for PVK by an oxidative route opens opportunities for the synthesis of new copolymers . Recently, Chemek et al prepared a new copolymer based on PVK, P3HT, and P6HT, while Melki et al have synthesized a new copolymer based on PVK and PEDOT via oxidative process. In these previous works, anhydrous FeCl 3 has been used as oxidant to increase the PVK polymerization and create a coupling site in the PVK skeleton …”

International audienceA novel diblock copolymer based on poly(N-vinylcarbazole) PVK and poly(p-phenylenevinylene) (PPV) precursor was synthesized by oxidative cross-linking. The grafting of PPV with PVK moieties was elucidated by infrared absorption analysis. A structural study by X-ray diffraction and a morphological study of the copolymer by scanning and transmission electron microscopy reveal a multiscale one-dimensional self-organization both at the molecular and at the sub-micrometric level. The resulting copolymer exhibits original optical properties compared to those of PVK and PPV ones and presents an improved thermal behavior

“…[7,8] Furthermore, due to its fine thermal property and narrow energy gap, poly(vinyl carbazole) (PVK) has a good prospect in the field of photoelectronics. [9] On the other hand, the thiophene materials have a good absorption over the whole visible light spectrum. If a single molecule bears both vinyl carbazole and thiophene groups, it will hopefully have outstanding thermal and photoelectric properties.…”

Combination of vinyl carbazole and thiophene groups’ excellent thermal properties and optical properties, a novel polymer named poly(2,7-bi-2-thienyl-9-vinyl-9-H-carbazole) was synthesized via radical polymerization and Suzuki reaction. The polymer was characterized using Fourier transform infrared spectrometer(FT-IR), gel permeation chromatography(GPC), differential scanning calorimetry(DSC), and X-Ray fluorescence spectrometer(XRF). It was found that this π-conjugated polymer containing vinyl carbazole and thiophene groups gave a high glass transition temperature (Tg=251°C). This feature made poly(2,7-bi-2-thienyl-9-vinyl-9-H-carbazole) possessing an excellent thermal performance.

“…Materials that combine properties of these two polymers (PVK and PEDOT) 16,17 are attractive materials for a variety of applications in the electronic devices, such as light-emitting diodes (LED) and field-effect transistors (FET). [18][19][20][21][22] Generally, the electric properties of polymers PVK and PEDOT are strongly governed by the intramolecular delocalization of p electrons along the conjugation chain.…”

ABSTRACT:We report a theoretical study of a new copolymer based on (Carbazole and Ethylenedioxythiophene) n (n ¼ 1-3) in their neutral and oxidized states, by using B3LYP/6-311G(d,p) calculations and thus deduce its optoelectronic properties. We discuss the influence of chain length of these properties. We also discuss the experimental UV-Visible spectrum for (PolyvinylcarbazolePoly(3,4-ethylenedioxythiophene)) (PVK-PEDOT) copolymer powder for comparison. Conformational analysis shows that there are no big changes in the structural parameters of the oligomers in their neutral form. After oxidation the oligomers become more planar and show a quinoidal character. The electronic states of monomers (Cbz-Edot) based Carbazole (Cbz) and Ethylenedioxythiophene (Edot), were elucidated by molecular orbital calculations using B3LYP/6-311G(d,p). The HOMO, LUMO, and gap energies E g were also deduced for the stable structure of the neutral, polaronic, and bipolaronic forms. Electronic transition energies and oscillator strengths of copolymers were obtained by the ZINDO, TD-DFT, and CIS methods. Band gaps of the corresponding polymers were obtained by extrapolating oligomer gaps to infinite chain lengths. These results will be compared with the experimental values obtained by optical spectrum. The optoelectronic properties of the (Cbz-Edot) 3 led us to suggest that this oligomer is a good model to reflect those of the parent polymer.
