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.

Under optical and electrical control, a multifunctional electro-optical dual-control color-changing and energy storage device not only realizes fast color conversion but also achieves good energy storage performance. In this work, Mo-doped WO 3 (Mo-WO 3 ) films were prepared by a one-step hydrothermal method, among which the 2 at. % Mo-doped WO 3 film has the best electrochromic and energy storage performance. Meanwhile, TiO 2 /NiO composite films were prepared by the hydrothermal method and electrodeposition method. The TiO 2 /NiO/N719 photoanode was prepared by the dip-dyeing method on the TiO 2 /NiO composite film. The results show that the TiO 2 /NiO-10s/N719 composite film has excellent photoelectric conversion and energy storage properties. Finally, choosing Mo-WO 3 as the cathode and the TiO 2 /NiO/N719 film as the anode, a multifunctional electrooptical dual-control Mo-WO 3 @TiO 2 /NiO/N719 color-changing and energy storage device was constructed. Under electrical control, it shows a fast color switching rate (the coloring/bleaching time is 4.1/2.9 s), excellent coloration efficiency (62.1 cm 2 /C), obviously improved area capacitance (90.4 mF/cm 2 ), and excellent cycle stability. Under optical control, it shows a shortened optical response time (the coloring/bleaching is 70.3/158.9 s), excellent coloration efficiency (58.2 cm 2 /C), better area capacitance (51.1 mF/cm 2 ), and excellent photoelectric conversion efficiency.
