Based on triphenylamine (TPA) and aromatic diamines, two multifunctional donor−π−acceptor (D−π−A) conjugated poly-Schiff bases (PSBs) were synthesized and subsequently tested and analyzed. The aforementioned conjugated PSBs exhibit electrochromic (EC) and electrofluorochromic (EFC) features and can be utilized as cathode electrode materials for aqueous Zn-ion batteries (AZIBs). Both polymer films, PTTB-1 and PTTB-2, show good EC and EFC properties, excellent dissolution processability, thermal stability, and reversible yellow-to-violet color changes in the UV−vis region. Between them, better optical contrast (46%), a fast response time (2.8 s/ 8.2 s), a high coloring efficiency (CE = 310 cm 2 C −1 ), and good cycling stability (10% attenuation over 2000 s of cycling) are all displayed by the PTTB-2 polymer. PTTB-1 and PTTB-2 present excellent EFC properties and solvatochromic effects. Full batteries constructed using a zinc anode, PSB cathodes, and 2 mol L −1 Zn(CF 3 SO 3 ) 2 aqueous solution show better rate performance, quicker reaction kinetics, and high cycling stability. The specific capacities of PAZIB-1 and PAZIB-2 reach 143 and 150 mA h g −1 , respectively, at a current density of 0.1 A g −1 . Furthermore, the specific capacities can still reach 93 and 102 mA h g −1 at a high current density of 6 A g −1 . Surprisingly, the full batteries exhibit outstanding cycling stability for long-term cycling (6 A g −1 , >5000 cycles). These innovative PSB materials, which integrate several functionalities, present more opportunities for the development of EC displays, AZIBs, sensing materials, and energy-efficient smart windows.

“…Numerous materials with electrolyte‐based ECDs have been developed for regulating the interior temperatures. [ 16–19 ] The construction of ECDs has recently been made simpler by the development of a versatile electro‐responsive switchable material that can act as both an electrochrome and an electrolyte. [ 20 ] This all‐in‐one design tackles problems often connected with solid or liquid electrolytes, such as the possibility of leakage and diminished transparency, alongside several others, while minimizing material waste.…”

Smart windows are gaining attention for their exceptional ability to regulate light and heat dynamics effectively. The main objective of developing dual‐responsive smart window materials lies in enhancing building applications and optimizing energy efficiency. Materials that exhibit dual responsiveness have already been reported in the literature. However, these materials have not garnered substantial research interest primarily due to prevailing economic and technological constraints. This study introduces a new methodology that uses a phase‐changing material as an electrolyte to design and customize smart windows based on individual preferences and requirements. In this paper, carboxymethyl cellulose sodium salt‐grafted copolymerpoly(2‐(dimethylamino) ethyl methacrylate)‐(N‐isopropylacrylamide)[CMC‐Na‐pDN] as an electrolyte and 1,1'‐Bis(2‐hydroxyethyl)‐4'4'‐dipyridinium hexafluorophosphate [HOEV] as a chromophore are synthesized and used to fabricate a gel‐based electro/thermochromic device (ETD). ETD exhibits dual‐chromism characteristics, transitioning from a colorless state to a purplehue at 25°C when 2V is applied. Furthermore, the purple color undergoes a transformation to blue coloration when the temperature exceeds 40°C. These phenomena arise due to the synergistic effect between its electrochromicreaction and thermochromic behavior. The ETD device exhibits a high optical constrast ∼82.5%, with a coloration efficiency (CE) of 333.1 cm2 C−1 and cyclic stability of >2000 cycles.

“…[ 9 ]. Recently, with the introduction of heteroatoms in the chain of the polymer, such as polythiophenes [ 10 ], and the use of the D-A-D method [ 11 ] it is possible to obtain greater control of the electrical properties of the materials improving electrochromic performances of the devices [ 12 ]. Due to its durability and low synthetic costs, Prussian blue offers fast transmittance switching properties with no memory effect that together with tungsten trioxide are used as electrochromic layers by in situ polymerization for the production of complementary electrochromic devices [ 13 , 14 ].…”

In this work, the implementation of an electrochromic device (10 cm × 10 cm in size) for energy saving applications has been presented. As electrochromic system has been used with an electrochromic solution (ECsol) made by ethyl viologen diperchlorate [EV(ClO4)2], 1,1′-diethyl ferrocene (DEFc) and propylene carbonate (PC), as solvent. The final system has been obtained by mixing the ECsol, described above, with a polymeric system made by Bisphenol-A glycerolate (1 glycerol/phenol) diacrylate (BPA) and 2,2-Dimethoxy-2-phenylacetophenone (Irgacure 651) in a weight percentage equal to 60:40% w/w, respectively. Lithography has been used to make a spacer pattern with a thickness of about 15–20 µm between the two substrates. Micro-Raman spectroscopy confirmed the presence of the EV•+ as justified by the blue color of the electrochromic device in the ON state. Electrochemical and optical properties of the electrochromic device have been studied. The device shows reversible electrochromic behavior as confirmed by cyclic color variation due to the reduction and oxidation process of the EV2+/EV•+ couple. The electrochromic device shows a variation of the % transmittance in the visible region at 400 nm of 59.6% in the OFF state and 0.48% at 3.0 V. At 606 nm the transmittance in the bleached state is 84.58% in the OFF state and then decreases to 1.01% when it is fully colored at 3.0 V. In the NIR region at 890 nm, the device shows a transmittance of 74.3% in the OFF state and 23.7% at 3.0 V while at 1165 nm the values of the transmittance changed from 83.21% in the OFF state to 1.58% in the ON state at 3.0 V. The electrochromic device shows high values of CCR% and exhibits excellent values of CE in both visible and near-infrared regions when switched between OFF/ON states. In the NIR region at 890 nm, electrochromic devices can be used for the energy-saving of buildings with a promising CE of 120.9 cm2/C and 420.1 cm2/C at 1165 nm.
