“…The furan-EDOT monomers, 5- [1,4]dioxin-5-yl)furan (EDOT-Fu-EDOT), were synthesized perviously by Stille coupling reaction, a convenient method for the formation of aromatic C-C bond, combining EDOT unit and furan unit to give the target compounds in satisfactory yields as we reported previously [32]. Dichloromethane (analytical grade; Beijing East Longshun Chemical Plant) was purified by distillation with calcium hydride under a nitrogen atmosphere before use.…”

“…Its monomer, 3,4-ethylenedioxythiophene (EDOT), has been employed as a building block in the design of conjugated systems, which incorporate unique properties such as capacitance properties [31]. Although the electrochemical properties and quality of obtained furan-EDOT copolymer films could be improved via incorporating the EDOT unit into polyfuran chain length [32], few studies have attempted to characterize the capacitance properties of furan-EDOT copolymer films.…”

A series of furan-EDOT copolymer films, namely, P(Fu-EDOT), P(Fu-EDOT-Fu) and P(EDOT-Fu-EDOT), were electrochemically synthesized from their corresponding monomers and evaluated as active electrode materials for supercapacitor applications by galvanostatic charge-discharge method. The specific capacitance of these copolymers was calculated to be 65, 46 and 75 F g -1 at a current density of 1 A g -1 , respectively. Besides, their energy density were also investigated. Among them, P(EDOT-Fu-EDOT) exhibited higher specific capacitance and energy density (15 Wh kg −1 at a power density of 0.6 KW kg −1 ) than P(EDOT-Fu) and P(Fu-EDOT-Fu), and also showed a large power range while maintaining a relatively high energy density. These favorable performances make P(EDOT-Fu-EDOT) a promising candidate as electrode material for supercapacitors compared with P(Fu-EDOT-Fu) and P(EDOT-Fu).

“…Recently, we developed several typical furan-based and thiadiazolo [3,4-c]pyridine-based polymers [32][33][34], such as polyfurans, polybifurans, polytrifurans [32], furan-EDOT polymers [33], and PEPTE [34], leading to the availability of promising furan-based polymer electrochromic materials. Considering advantages of furan-based copolymers, furan was employed as a building block for the design of donor-acceptor system.…”

Two novel furan and pyridinechalcogenodiazole based monomers, namely 4,7-di(furan-2-yl)-[1, 2, 5]thiadiazolo [3,4-c]pyridine (Fu-S-Fu) and 4,7-di(furan-2-yl)-[1, 2, 5]selenadiazolo [3,4-c]pyridine (Fu-Se-Fu), where a single atom in the pyridinechalcogenodiazole unit is varied from S to Se, were designed and synthesized via a donoracceptor approach, and then the corresponding polymers, P(Fu-S-Fu) and P(Fu-Se-Fu), were electrosynthesized. Also, structure characterization and optoelectronic properties, including FTIR, SEM, DFT theoretical calculations, intramolecular charge transfer nature, optical and electrochemical behaviors, and electrochromic performance, were systematically investigated and comparatively discussed. The obtained monomers exhibited lower oxidation potential (Fu-S-Fu: 1.12 V; Fu-Se-Fu: 1.09 V), leading to the facile electrodeposition of uniform hybrid polymer films with outstanding electroactivity at low oxidation potentials. Optical spectroscopy of corresponding polymers showed that Se substitution led to a redshift in the low-energy transition, while the high-energy band remains relatively constant in energy.

“…On the other hand, several researches have been focused on the copolymerization in order to prepare conducting polymers with better properties and to overcome the limitation of the rarity of new monomers. New monomers can be synthesized from available monomers and used to prepare new polymers having collection of properties of both monomers [33][34][35]. Ng and Xu Scheme 1.…”
