“…The preparation of poly(N-vinylcarbazole) (PVCz) by electrochemical polymerization has been known for many years [1][2][3][4]. The first stage of electropolymerization involves the oxidation of monomer to the cation radical.…”

“…Only a few papers have described the electrodeposition of films from carbazole and their properties [15][16][17]. On the other hand, the anodic oxidation of N-ethyl carbazole (ECz) in acetonitrile does not produce films [15] except on Au and glassy carbon electrodes in aqueous HClO 4 with conductivities of between 10 Ϫ 8 and 10 Ϫ 4 S/cm [18]. As noted above the oxidative polymerization of carbazoles by using metal salts have not been investigated systematically so far.…”

Poly(N‐vinylcarbazole), poly(N‐carbazole) and poly(N‐ethylcarbazole) powders were chemically synthesized by the reaction of ceric ammonium nitrate (CAN) with N‐vinylcarbazole carbazole and N‐ethylcarbazole in acetonitrile. Products were characterized by elemental analysis, Fourier transform infrared spectroscopy, scanning electron microscopy and viscosity, X‐ray fluorescence and four‐probe conductivity measurement. It is found that when a suitable concentration of CAN is used in the polymerization process, the conductivity of chemically synthesized polymers can be improved further by controlling the CAN addition. © 1997 John Wiley & Sons, Ltd.

“…The electrochemical polymerization of NVK proceeds through an electrochemical-chemical-electrochemical mechanism [23][24][25][26] (Scheme 1), which starts with the oxidation of the monomer to the corresponding cation radical (1 → 2) followed by a fast dimerization at position 3 of the carbazole unit (2 → 3). The two-electron oxidation 3 → 4, which occurs at less positive potential than that required for the oxidation of the monomer, leads to the formation of a dimer bonded between the carbazole units (4).…”

“…When dimerization occurs, H + ions split off and provoke the polymerization of NVK through its vinyl group. The attack of these protons (H + ) to the vinyl group of the growing electron-conducting polymer (4 → 5), causes cross-linking (5 → 6), whereas the activation of the vinyl group of the monomer in solution leads to the formation of a photo-conducting polymer (structure 8, Scheme 2) [23][24][25][26]. The deposited poly(3,6-N -vinylcarbazole) formed on the anode surface, here named P3,6NVK, exhibits different cross-linking degrees (m in structure 6, Scheme 1) depending on the synthesis conditions.…”

Recently, we investigated the effect of two different basic additives on the anodic polymerization of N -vinylcarbazole [39].…”

Poly(3,6-N-vinylcarbazole) (PVK) films were prepared by electrochemical oxidation of N-vinylcarbazole on a platinum electrode using acetonitrile as solvent and tetraethyl ammonium tetrafluoroborate as electrolyte. The electro-synthesis was carried out using electrical potential cycling in the presence of tetraethylammonium phthalate. The presence of this salt in the electrolyte decreased the cross-linking of the electrodeposited polymer to give PVK bearing a more uniform morphology, with higher thermal stability and electrical conductivity than PVK obtained without acidity control. PVKs were characterized by FT-IR and absorption spectroscopies, thermogravimetric analysis, differential scanning calorimetry and four-probe electrical conductivity measurements. Thermal, optical properties and conductivity of the obtained polymers were compared to those of traditional PVK.

Conjugated microporous polymers (CMPs) are a unique class of porous materials that have an integrated π‐conjugated system and permanent intrinsic porosity. They are of great interest because of their outstanding performance in gas sorption, photoredox catalysis, energy storage, organic light‐emitting diodes (OLEDs), and sensing applications. However, conventional chemically synthesized CMPs are solid powders and have poor solubility, which makes it difficult to process and integrate devices, and has become a bottleneck preventing their practical applications. Electropolymerization (EP) is a simple and efficient method for the preparation of CMP films, which simultaneously completes material synthesis and film processing. More importantly, the microstructure of the CMP films can be effectively controlled by electrochemical parameters. In this review, first, the basic synthetic principles and strategies of CMP films via EP are introduced, allowing for facile optimization of the structure and properties. Then, the recent progress of the EP CMP films is focused upon in organic electronics, energy storage, sensors, chemical capture and separation, and electrocatalysts. Finally, the challenges and outlook for EP CMP films are addressed.
