“…Very recently, Gao et al synthesized a UV–curable acrylate-functional viologen to deposite polyviologen films on indium tin oxide (ITO) electrode surface [57]. The simple and scalable UV curing approach resulted in polyviologen films with good chemical stability and excellent adhesion between the polymer film and the ITO glass.…”

Organic materials have gained considerable attention for electrochromic (EC) applications owing to improved EC performance and good processability. As a class of well-recognized organic EC materials, viologens have received persistent attention due to the structural versatility and property tunability, and are major active EC components for most of the marketed EC devices. Over the past two decades, extensive efforts have been made to design and synthesize different types of viologen-based materials with enhanced EC properties. This review summarizes chemical structures, preparation and EC properties of various latest viologen-based electrochromes, including small viologen derivatives, main-chain viologen-based polymers, conjugated polymers with viologen side-chains and viologen-based organic/inorganic composites. The performance enhancement mechanisms are concisely discussed. The current marketed viologens-based electrochromic devices (ECDs) are briefly introduced and an outlook on the challenges and future exploration directions for viologen-based materials and their ECDs are also proposed.

An electrochromic material is one that has the ability to change its color reversibly to undergo redox reactions when stimulated by an electrical current or by an adequate potential difference. The electrochromic materials can be classified as transition metal oxides, intercalation materials or organic materials. This work has proposed to do a brief review of the class of organic electrochromic materials, giving greater emphasis to subclasses of viologens, phthalocyanines and transition metal complexes. These materials have a wide technological application, such as windows controllable transmittance (smart window) displays, rear-view mirrors for vehicles, among other applications.

“…Viologens (1, 1'-disubstitued-4, 4'-bipyridine salts) with extended π-conjugation, can exhibit excellent photochromic and electrochromic characteristics, excellent fatigue resistance, and good environmental stability (1-3) when they were in their crystalline states (4), dispersed in appropriate aprotic matrixes (5), incorporated polymers by copolymerization, or graft-modified reactions (6)(7)(8)(9). Hyperbranched polymers possess unique structures such as three-dimensional dendritic architecture, globular conformation, amorphous nature, and multi-functionality at end groups, which impart them unique physical and chemical properties such as good solubility, low viscosity, and easily graftmodified (10 out modified and functionalized reaction for hyperbranched polymer such as end capping, terminal grafting, surface growing, hypergrafting, hybrid blending, and so forth.…”

Styrene-functional hyperbranched viologen (SHBV 2+ ) was successfully synthesized and characterized in detail by FTIR, 1 H NMR, and XPS spectra, respectively. Subsequently, it was cured by visible light to obtain cross-linked hyperbranched viologen film. It is noteworthy that cross-linked SHBV 2+ film possessed better photochromic and electrochromic performances. After UV illumination for 60 s, the cross-linked SHBV 2+ film can swiftly change its color from pale yellow to deep bluish violet, whereas the absorbance of SHBV 2+ film at 610 nm did not change significantly and was still retained about 0.423 after 20 coloring/bleaching cycles. The single-type SHBV 2+ EC device can undergo reversible color change in response to the alternate external voltages of −2.0 V and 2.0 V, respectively, while the changes in optical transmission and charge density of EC device at 550 nm did not deteriorate significantly and still remained about 48.2% and 13.85 mC·cm −2 after 10 coloring/bleaching cycles. Furthermore, single-type SHBV 2+ PEC device possessed better optical writing and electrical erasing performances. After 10 repeated writing/erasing cycles, the contrast did not decrease significantly and still remained about 48.0%, while the electrical erasing time did not deteriorate significantly and remained about 22.0 s. This device can realize rapid storage, modulation, and erasing of optical information.
