“…4 insets) glass/SnO2/PEDOT/electrolyte/PB/SnO2/glass configuration [8], which resemble the ECD with WO3 and gelatin-based electrolyte [30,31]. However, they are similar to the voltammograms obtained for ECD with poly(vinyl butyrate) (PVB) electrolyte [32]. The presence of these additional peaks can be due to the PB redox properties, described in Equation (2), where transition PB↔PG (Prussian blue ↔ Prussian green) can occur due to the applied potentials of -2.6 to 2.0 V during this analysis [13].…”

“…Hence, PVB has been used as a matrix to host the electrolyte. The ionic conductivity of this ionic‐conducting PVB electrolyte ranges from approximately 10 −5 to 10 −7 S cm −1 , which is within acceptable limits for typical EC devices . Nevertheless, it is still a challenge to realize a stable and flexible EC due to the limited availability of flexible polymeric electrolytes with high ionic conductivity.…”

Electrochromic (EC) technology has progressed tremendously in recent years. Rigid EC devices have advanced to offer additional attractive physical attributes such as flexibility, stretchability, and foldability. These features are appealing for wearable and futuristic technologies, and hence serve to revolutionize EC applications toward deformable electronics. In this review, the essential prerequisites of each component of the flexible EC devices are delineated, such that each component is mechanically flexible to maintain the structural integrity of the device. The recent progress in flexible EC performance is discussed, from flexible to stretchable and the foldable device being the latest trend in deformable electronics. Next, we address the pertinent challenges often encountered in the fabrication of flexible EC devices and outline the adopted strategies from the literature to this point. Finally, the concept of the multifunctional EC device is discussed for achieving versatile emerging applications. We envision that this review will shed light on the properties of flexible ECs and shape the new milestones to be set for realizing a more versatile multifunctional EC device.

“…For instance, a multifunctional material could be designed for a window to be electrochromic and/or photochromic during the day to reduce/modulate solar heat gain while remaining EFC at night for displays or lighting. [ 32 ] The challenge for realizing this conceptual design is to find a stable organic dye platform that shows the reversible, high contrast, multichromic, and long‐term stability seen with the viologens and polymeric materials while also exhibiting the photochromism and high fluorescence quantum efficiency (Φ F ).…”

There have been an increasing number of materials developed that show multifunctional chromogenic properties (such as electrochromism, electrofluorochromism, or photochromism), but to date, few materials have shown all three properties. Materials that are electrochemically and optically active are attractive for a diverse set of applications that include smart‐windows, lighting, sensing, energy production, and conservation. This is especially attractive for building developers interested in adaptive or environmentally responsive façades. Achieving systems made from cost‐effective, readily synthesized materials will make them easy to utilize in a variety of fields. Low‐cost devices are developed using water‐soluble, chromogenic thiazolo(5,4‐d)thiazole (TTz) dyes that show high device performance in three areas: electrochromism, electrofluorochromism, and photochromism and are all contained within a highly fluorescent aqueous polyvinyl alcohol/borax hydrogel device. The dyes incorporate a rigid, heterocyclic TTz structure that enables the development of devices with excellent reversibility and stable cycling for 250 cycles. The TTz hydrogel‐containing devices also exhibit photochromism under illumination, which can be electrochemically cycled back to the colorless state. In addition, coupling photochromism with electrochromism lowers the power necessary for a comparable electrochromic color change. Last, the hydrogel‐containing devices also show electrofluorochromism, where fluorescence can be turned off by > 90%.
