“…Macromolecules end-capped carbazole moieties were also used as luminescent films electrodeposited (ED) with good electropolymerization behaviors and properties [10]. Likewise, polymers bearing carbazole structure has been widely described [14][15][16][17][18][19], e.g., fluorescent carbazolyl-labeled polysiloxanes [14]. A green light-emitting phosphorescent and polymeric light-emitting diode (PLED), containing a layer of a carbazole-oxadiazole copolymer showed a high efficiency, current densities, and luminance levels [15].…”

A series carbazolyl-containing polymers were synthesized by anionic polymerization of various oxiranes and methyl methacrylate. The polymerization was carried out using as initiator carbazylpotassium activated 18-crown-6 in THF. The polymers were prepared and found using size exclusion chromatography to have a degree of polymerization (DP n ) about 20 relatively and low dispersity in the range of 1.07-1.66. Their optical properties were investigated by means of UV-vis and photoluminescence spectroscopies. The obtained polymers emitted light with maximum emission about 370 nm and high quantum yield ranging up to 79 %. Thus, it was confirmed that the utilization of fluorophore initiator for polymerization of non photoresponsive monomers is quite efficient for the preparation of photoluminescent polymers.

“…New electroactive polymers with carbazole conjugated-aliphatic nonconjugated repeating units in the main chain have been reported. [16]. High, blue photoluminescence activity of segmented polyethers containing oxadiazole/carbazole units and flexible aliphatic moieties have also been described [17,18].…”

A novel synthesis of 3,6-bis (2,3-dihydrothieno[3,4-b] (2,3-dihydrothieno [3,4-b][1,4]dioxin-5-yl)-9-tosyl-9H-carbazole (EDOTTsCz) was synthesized and electrochemically polymerized on glassy carbon electrode (GCE) in 0.1 M tetrabutyl ammonium tetrafluoroborate (NB 4 BF 4 )/acetonitrile (CH 3 CN). Alternating copolymer was formed by CV method. Modified polymer electrode was characterized by Fourier transform Infrared Spectroscopy-Attenuated Transmission Reflectance (FTIR-ATR), Cyclic voltammetry (CV), Scanning electron microscopy-Energy dispersive X-ray analysis (SEM-EDX), Atomic force microscope (AFM) and Electrochemical impedance spectroscopy (EIS). Capacitive behaviors of the modified GCE were defined via Nyquist, Bode-magnitude, Bode-phase and Capacitance plots. A modified copolymer electrode provides enhanced capacitance evaluation, which may results in performance in energy storage devices.

“…19 Dicarbazoles connected with various etheroxide spacers or carbon chains have been investigated. [20][21][22][23][24] The increasing polymerization positions, together with the flexible spacers between the chromophores, lead to the crosslinked polymer structures. Owing to the ease of formation of relatively stable radical cations (polarons), carbazoles readily polymerize in electrochemical polymerization processes.…”

A copolymer based on 1,12-bis(carbazolyl)dodecane (2Cz-D) and 3,4-ethylenedioxythiophene (EDOT) was electrochemically synthesized in dichloromethane containing 0.1-M tetrabutylammonium tetrafluoroborate. Cyclic voltammetry, Fourier-transform infrared, morphological and elemental analyses confirm that the resultant polymer is a copolymer rather than a composite or a blend of the two homopolymers. The copolymer exhibits good redox activity and high electrochemical stability. In contrast with powdered poly(3,4-ethylenedioxythiophene) (PEDOT), the copolymer formed in this study exists in a free-standing film state, and it has a higher thermal stability and better mechanical properties. Moreover, the copolymer films emit blue light, depending on the monomer feed ratios. The thermoelectric properties of the copolymer films were also investigated. Because the 2Cz-D/EDOT feed ratios were different, the electrical conductivities of the obtained copolymer films were improved to varying degrees compared with that of the poly(1,12-bis(carbazolyl)dodecane) (P2Cz-D) film. The highest obtained electrical conductivity was 0.6 S cm À1 , four orders of magnitude higher than that of P2Cz-D (2.7Â10 À5 S cm À1 ). The Seebeck coefficients of the copolymer films were also modified compared with that of P2Cz-D. All of these enhanced properties will be beneficial to the potential applications of these materials in polymer optoelectronics or as organic thermoelectric materials.
