Among conducting polymers, polycarbazoles are known for their good electro-activity [1,2] and thermal [3][4][5], electrical [6], photo-physical [7], and electrochromic properties [8]. They have been suggested for a number of applications, such as electroluminescent devices [9], sensors [10,11], redox catalysts [12], and electrochromic displays [13]. The functional groups, such as amino, imino and sulfonic groups have been performed for achieving new polymers which meet the criteria of commercial applications [14][15][16]. There are many novel syntheses of functional polycarbazole papers. 3,6-bis (2,3-dihydrothieno [3,4-b] N-(o-ethynyl) Abstract. A novel synthesis of 4-toluene 9H-carbazole-9-carbodithioate (TCzC) was chemically synthesized and characterized by Fourier Transform Infrared (FTIR), proton nuclear magnetic resonance ( 1 H-NMR), and carbon nuclear magnetic resonance ( 13 C-NMR) spectroscopies. Specific (C sp ) and double layer capacitances (C dl ) of the electro-coated poly(carbazole) and poly(TCzC) films were obtained on glassy carbon electrode (GCE) by impedimetric method with DC potential from -0.1 to +1.0 V by increasing potential of 0.2 V. The polymers were characterized by Cyclic voltammetry (CV), Fourier transform infrared reflectance-attenuated total reflection spectroscopy (FTIR-ATR), Atomic force microscopy (AFM), and Electrochemical impedance spectroscopy (EIS). The use of additional variable (DC potential) helped to disambiguate the equivalent circuit model of R (C(R(Q(RW))))(CR).Simulation results were compared with experimental data. In this study, substituted group effects of CS 2 and tosyl on carbazole polymer were investigated by EIS technique. CS 2 group together with tosyl group in the structure of carbazole decreased the specific capacitance value (C sp = 0.43 mF·cm -2 ) compared to PCz (C sp = 1.44 mF·cm -2 ). Electropolymerization formation was seriously affected by substituted groups of CS 2 and tosyl on conjugation system because of the electron donor and acceptor ability.

Here, we described a novel synthetic method of PVP (poly(N-vinyl-2-pyrrolidone))-coated GeO 2 nanoparticles by a simple procedure, and its fabrication into a poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT-PSS) film. Interestingly, PEDOT-PSS films containing a small amount of PVP-coated GeO 2 nanoparticles exhibited higher electrical conductivity than pure PEDOT-PSS. Finally, we have succeeded in the development of a new organicinorganic thermoelectric conversion film with high performance.The energy systems of many nations dependence on fossil fuels, and therefore, worldwide demand for renewable energy is expected to expand.1 CO 2 derived from fossil fuels is enormous and is a factor that promotes global warming. Recently, new energy without CO 2 emission has attracted considerable attention and the development of thermoelectric conversion materials that convert thermal energy into electric energy has been reported.2 In particular, a thermoelectric conversion element composed of an organic material with an electronic carrier (such as a conductive polymer 3,4 and a polymer complex 5,6 ) has advantages of lightweight, mechanical flexibility, low cost, and is a material with extremely high potential.7 Furthermore, it does not use rare metals as inorganic heat electric materials and is low cost. Generally, the thermoelectric conversion efficiency is defined as the dimensionless figure of merit ZT value.where S, ·, ¬, and T are Seebeck coefficient, electrical conductivity, thermal conductivity, and temperature, respectively. Thermoelectric material with high ZT and power factor PF (=S 2 ·) are desirable, yet there remains a trade-off between · and S.Many researchers have worked on the development of organic thermoelectric materials using conductive polymers 8 since we reported stretched polyphenylenevinylene derivatives with ZT = 0.1. 9 According to the recent investigations, Pipe and co-workers have demonstrated that a poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT-PSS) film with a record value of ZT = 0.42 by optimization of the doping level.
