“…Organic electrochromic semiconducting polymers, which are capable of changing their colour upon applied electrochemical potential, in the design are revolutionary multifunctional materials, which already are being successfully applied in smart windows, [1][2][3] switchable mirrors [4] and displays. [5] Moreover, a development of smart windows which can regulate transmission of visible and near-infrared light, thereby reducing the energy costs for building air conditioning, is important for the nowadays technology.…”

An electrochromic material based on azobenzene and 3,4-ethylenedioxythiophene (EDOT) semiconducting layer was electrochemically deposited on an indium tin oxide coated glass electrode. Chemical synthesis of the azobenzene and EDOT-based chromophore (DAE) and electrochemical formation of its corresponding polymer (pDAE) are reported. The electrochromic properties of the synthesized polymer pDAE were investigated by electrochemical and spectroelectrochemical methods. pDAE exhibited an optical bandgap of 1.82 eV and three distinct colored states in its reduced, neutral, and oxidized forms. The pDAE polymer showed 44 % optical contrast at 710 nm between its reduced and oxidized states and a fast electrochromic switching time of 1.0 s. The frontier molecular orbitals, Raman shifts, and semiconducting properties of this electrochromic polymer were evaluated by density functional theory calculations. The optical absorption bands of the polymer charged states were assigned and investigated.

“…Further efforts have extended this method to attach different functional groups to the polymer backbone, including alkyl, phenyl, and pyridinyl groups . Aryl rings can also be attached to the 2,5‐dithiophenylpyrrole unit via a linker . We are especially interested in the direct incorporation of N‐aryl group, which allows for electronically coupled functionality that can introduce organization by increased π‐stacking or enhance light absorption, both of which are of interest for the design of active materials in photovoltaic devices .…”

A modular facile route has been developed to synthesize functionalized 2,5-di(thiophen-2-yl)-1-H-arylpyrroles from readily available starting materials. These units are compatible with various polymerization conditions and are versatile building blocks for conjugated polymers. The polymers show high thermal stability and solubility in a number of solvents. Characterization of the polymers reveals a correlation between molecular packing, controllable by polymer design, and charge carrier mobility.

“…4,5 Moreover, the 1,3,5-triazine unit possesses structural symmetry and high electron affinity. 6 This makes them promising materials for several applications such as light-emitting devices (LED), chemiresistors, electrochromic devices (ECDs) [7][8][9][10] and sensors. [11][12][13] Electrochromism is a reversible and visible change in transmittance and/or reflectance that is coupled with an electrochemically induced oxidation-reduction reaction.…”

A novel triazine-based, star shape and electroactive monomer, 2,4,6-tris(2-(9H-carbazol-9-yl)ethoxy)-1,3,5-triazine (TCZ) which contains 2,4,6-trichloro-1,3,5-triazine as the core and 2-(9H-carbazol-9-yl)ethanol as the arms, was successfully synthesized. After electrochemical polymerization of the TCZ monomer, called PTCZ, the polymer shows superior optoelectronic and thermal properties due to its unique three-dimensional shape and highly-branched structure in comparison with linear analogues. Electrochromic studies exhibited that PTCZ has turquoise color in the oxidized state and is transparent in the neutral state. Due to the fact that the redox color characteristics of PTCZ are indispensable for smart windows, a PTCZ-based electrochromic device was formed with PEDOT as complementary coloring material. A potential range of -1.5 to +1.8 V was determined to be suitable for operating the PTCZ/PEDOT device between transparent and blue colors. Characterizations of the device were performed in term of switching times, optical contrast, optical memory and redox stability.
