“…Unlike the electrodeposition of metals, a reductive electrochemical formation of thin, homogenous, and insoluble conductive polymer layers directly on the electrode surface is not a widely used method [ 120 , 121 , 122 ]. Typically, thin films of polymers derived from pyridyl and polypyridyl complexes containing styrene groups and complexes containing vinyl-substituted ligands are synthesized by electrochemical cathodic processes.…”

In the last few decades, the development and use of thin films and nanostructured materials to enhance physical and chemical properties of materials has been common practice in the field of materials science and engineering. The progress which has recently been made in tailoring the unique properties of thin films and nanostructured materials, such as a high surface area to volume ratio, surface charge, structure, anisotropic nature, and tunable functionalities, allow expanding the range of their possible applications from mechanical, structural, and protective coatings to electronics, energy storage systems, sensing, optoelectronics, catalysis, and biomedicine. Recent advances have also focused on the importance of electrochemistry in the fabrication and characterization of functional thin films and nanostructured materials, as well as various systems and devices based on these materials. Both cathodic and anodic processes are being extensively developed in order to elaborate new procedures and possibilities for the synthesis and characterization of thin films and nanostructured materials.

Electrochromic devices have emerged as new age technology devices due their low power consumption, eye friendly working modes, and simple structure with easily adjustable features. Such devices have vast application prospects in areas like energy efficient building architecture, flexible displays, next generation smart wearables, satellite thermal control, etc. Organic electrochromic material offers several advantages, including rich color, stretchable and flexible architecture, facile synthesis, and easy modification of optical properties. However there are certain technical issues, such as cyclic stability, durability, uniform color performance, etc, which are still to be resolved before large scale commercialization of organic electrochromic devices can occur. In recent years, various research teams have made efforts in developing new methods and technologies to overcome such issues. Here, we have summarized these innovative efforts taken in the last decade to help researchers analyze and compare different techniques adopted toward improving the performance of organic electrochromic devices.

Electrochemistry and Electrochromic Performance of a Metallopolymer Formed by Electropolymerization of a Fe(II) Complex with a Triphenylamine‐Hydrazone Ligand

The complex of Fe(II) ions of general formula [FeL2](BF4)2 with triphenylamine‐hydrazone ligand L has been synthesized and characterized. Oxidative electropolymerization of the complex proceeded smoothly on the working electrode producing a homogenous thin film of metallopolymer. The film thickness and morphology of the layer was investigated by microscopy techniques such as scanning electron microscopy and atomic force microscopy, and the composition of the film was confirmed by X‐ray photoelectron spectroscopy analysis. It was found that fifty successive oxidation/reduction cycles resulted in a 120 nm thick film on the electrode surface. The metallopolymer was also characterized using cyclic voltammetry and spectroelectrochemical methods. The film was found to change its color from yellow to green‐blue, exhibit high change in transmittance of 60 % at 770 nm, and possess good electrochemical stability during 375 cycles of switching of the potential between −0.1 V and +1.5 V, owing to the presence of metal ions that link two ligand molecules resulting in formation of highly cross‐linked film. The switching times (coloration and bleaching) were calculated to be 34.2 s and 7.3 s, respectively. Coloration efficiency of the formed film of polymeric complex was found to be 144 cm2 C−1.
