Electroconducting polymers from the group of synthetic metals are extensively investigated due to numerous properties perspective in practical application. These materials may be synthesized by both chemical and electrochemical procedures. Chemical synthesis is suitable when bulk quantities of the polymer are necessary and up to date it presents dominant commercial method of producing electroconducting polymers. Nevertheless, the electrochemical synthesis has its advantages; it avoids usage of oxidants since conducting polymeric material is obtained at anode upon application of positive potential, leading to increased purity. On the other hand, since the polymer is deposited onto electrode, further electrochemical characterization is facilitated. Owing to actuality of the research in the field, this text aims to describe important aspects of electrochemical synthesis of electroconducting polymers, with special emphasis to polyaniline and polypyrrole.

1,4-benzodioxan-based polydithienylpyrrole (PBDO) is electrochemically synthesized. Cyclic voltammograms are acquired to examine the redox properties of the PBDO films at various scan rates. Spectroelectrochemical and colorimetric studies are also conducted. The PBDO homopolymer has a bandgap of 2.38 eV and displays yellowish-green to bluish-violet coloration upon doping. Electrochromic devices (ECDs) that employ PBDO as an anodic polymer and poly(3,4-(2,2-diethylpropylenedioxy)thiophene) (PProDOT-Et 2 ) (or poly(3,4-ethylenedioxythiophene) (PEDOT)) as a cathodic polymer are constructed. The PBDO/PProDOT-Et 2 ECD shows higher T max (32.3%) and coloration efficiency (η, 437.5 cm 2 C −1 ) at 586 nm than those of PBDO/PEDOT ECD ( T max = 20.2%, η = 152.0 cm 2 C −1 at 606 nm). The PBDO/PEDOT and PBDO/PProDOT-Et 2 ECDs show satisfactory optical memories and redox stability.In the last two decades, π-conjugated polymers such as carbazole, triphenylamine (TPA), thiophene-based materials, and their derivatives have attracted considerable interest because of their widespread use in artificial muscles, 1 smart windows, 2 electrochromic devices (ECDs), 3-6 light-emitting diodes, 7-9 catalyst supports, 10-12 photovoltaics, 13,14 and fluorescence sensors. 15-17 Applications of π-conjugated polymers in the fields of electrochromic materials and energy-saving smart windows have attracted widespread attention in both academic and industrial communities. The various types of electrochromic materials may be divided into two general classes: inorganic electrochromic materials (transition metal oxides) and organic electrochromic materials (conducting polymers and viologens). π-conjugated polymers as eletrochromic materials have attracted attention because of their outstanding advantages over transition metal oxides, such as long-term stability, high optical contrast ratio, fast response time, high coloration efficiency, 18 low switching potential, and broad color availability through fine-tuning of their bandgap via modifications of their chemical structures. 19 The design and synthesis of new π-conjugated polymers and improvement of their switching ability are issues currently being investigated by researchers.The π-conjugated polymers used in electrochromic materials are mainly polyaniline (PANI), 20 polypyrrole (PPy), 21 polythiophene (PT), 21 polycarbazole, 22 polytriphenylamine, 23 and poly(3,4-ethylenedioxythiophene) (PEDOT). 24 Among these electrochromic conjugated polymers, PTs have been dominant due to their high conductivity, good redox reversibility, swift change of color with potential, and environmental stability. 25 Recently, various strategies have been proposed to fine-tune the colored neutral state of PTs. 26 PEDOT, an important PT derivative, contains two electron-donating oxygen atoms on the 3,4-positions of thiophene. PEDOT is usually used as a cathodically coloring material in ECDs. Poly(2,5-dithienylpyrrole) (PSNS) derivatives are also potential PT derivatives due to their low oxidation potential and facile che...

Three dithienylpyrrole-and tris[4-(2-thienyl)phenyl]amine-containing copolymers (P(MPS-co-TTPA), P(MPO-co-TTPA), and P(ANIL-co-TTPA)) were deposited on indium tin oxide (ITO) surfaces using electrochemical polymerization. Spectroelectrochemical characterizations of polymer films revealed that P(MPS-co-TTPA) film was light olive green, greyish-green, bluish grey, and grey in neutral state, intermediate state, oxidized state, and highly oxidized state, respectively, whereas P(MPO-co-TTPA) film was green moss, foliage green, dark greyish-green, and bluish-grey in neutral state, intermediate state, oxidized state, and highly oxidized state, respectively. The ∆T max of P(MPS-co-TTPA) film at 964 nm, P(MPO-co-TTPA) film at 914 nm, and P(ANIL-co-TTPA) film at 960 nm were 67.2%, 60.7%, and 67.1%, respectively, and the coloration efficiency (η) of P(MPS-co-TTPA) film at 964 nm, P(MPO-co-TTPA) film at 914 nm, and P(ANIL-co-TTPA) film at 960 nm were calculated to be 260.3, 176.6, and 230.8 cm 2 C −1 , respectively. Dual type complementary colored electrochromic devices (ECDs) were constructed using P(MPS-co-TTPA), P(MPO-co-TTPA), or P(ANIL-co-TTPA) as anodic copolymer layer and PProDOT-Et 2 as cathodic polymer layer. P(MPO-co-TTPA)/PProDOT-Et 2 ECD revealed high ∆T (55.1%) and high η (766.5 cm 2 C −1) at 580 nm. Moreover, P(MPS-co-TTPA)/PProDOT-Et 2 , P(MPO-co-TTPA)/PProDOT-Et 2 , and P(ANIL-co-TTPA)/PProDOT-Et 2 ECDs showed satisfactory long-term cycling stability and optical memory.
